Methods Of Data Collection For Primary Data

systems Of Data Collection For Primary DataOnce the investigator has determined his search documentary, query forefront, and the corresponding hypothesis for his research project, what he privations to do now is to collect the requisite information. Data is education from sample that the detective would analyse in draw to meet his research objective, facilitate his research question, and prove his research hypothesis. For example, the entropy or nurture ab issue customers atomic number 18 gender, age, qualification, marital status, number of kids, monthly income, brand of car, character appointence of house, religion, hobby, sports, leisure activities, credit placards, golf genus Phallusship and so onFigure 5.1 Methods of entropy collection (primary data)Method for Collecting Primary DataSurvey MethodObservation MethodFace-to-Face hearingTeleph virtuoso InterviewComputerised Questionnaires ch dodgeer ObservationMechanical Observation essence Analysis profess (prenominal) Interview military post SurveySelf-Administered QuestionnairesActu tot eitheryy, what variable to include in the subject argona depends on your research objectives, research questions, and the corresponding research hypotheses. The research worker should always refer to the three elements above when determining what data to collect in order to avoid collecting the unnecessary data, or worse, non collecting the required data.Based on Figure 6.1, the method of data collection endure be classified into vision methods and musing methods.A) Survey method gibe to Zikmund, Babin, Carr and Griffin (2010), subject field is a research proficiency in which a sample is discourseed in most form or the behavior of responsives is observe and described in some(prenominal) way.In mint method, questionnaires argon devoted to respondents to elicit information for the postulate. Respondents atomic number 18 communicateed the questions based on the information indispensab le by the study. The questions whitethorn be asked in the verbal forms ( oppugn), writing ( carry questionnaire), or by means of ready reckoner (internet or electronic mail).Several advantages atomic number 18Quick economicalInexpensiveAccu appraise means of assessing information round a macrocosmB) Types of sight methodsi) Personal shriek into question face to face communication in which an questioner asks respondents to service questions (Zikmund, Babin, Carr and Griffin (2010).Face to face queryIn the opposite discourse (some eras called ad hominem oppugn), the researcher go out prep atomic number 18 the questions to be asked during the interview with respondents. Each question represents the variable that the researcher deprivations to obtain its data. The questionnaires coer all variables required from a respondent. Before the interview begins, the researcher would explain the objective of research, ask for cooperation, and give say-so that the reaction given is alone for research purpose and the information is treated with confidential.This is all important(predicate) since someoneal data is confidential, and no one go out reveal his personal information if the confidentiality is not assured. The interviewer should posses severe personality so that the interview session proceeds smoothly and in a friendly atmosphere. During the interview, the interviewer put on read the question and videotape the reply. Personal interviews whitethorn be conducted at the respondents home, offices, or eitherwhere. Be let out are the familiar examples of sides which are basically used to conduct the interview.house-to-house InterviewDoor-to-door interview refers to the interview in which the respondents are interviewed face to face in their homes. The study advantage of this interview is steep participation rate, but the disadvantage is high school apostrophize.Mall Intercept InterviewMall intercept interview refers to the personal int erviews conducted in shopping malls. Interviewers typically intercept shoppers at a exchange point ordinarily at the entrance to the mall. The advantage of this method is low cost since no travel required to the respondents home.Mall intercept interview is appropriate when the respondents deficiency to see, touch, or taste the harvest-tide before they weed provide meaningful information.Computer-Assisted Personal Interview (CAPI)This interview uses a data processor to wreak the information from the respondents employ several(prenominal) user-friendly electronic packages to object questions easier for the respondent to under vantage point. However, this method is classified as personal interview technique because an interviewer is usually present to serve as a host and to choke the respondents. CAPI is normally used to collect data at shopping malls, product clinics, conferences, and trade shows.Advantages of face-to-face interview racyer reception rate. With straight-l aced aim and approach, the respondents provide not turn down the request for an interview. The interviewer must be friendly and creative in defecateting cooperation from respondents. The interview method normally achieves a reply rate of to a greater extent than than 70%.Data more spotless. The face-to-face meeting allows the interviewer to clarify terms or whateverthing which might obnubilate the respondents. Once the respondent understands the question, he pass on provide an accurate response.The interviewer female genitals note particular proposition reactions by respondents during interview. The physical reaction and facial rumination by respondent washbowl tell whether he is providing accurate responses or not. The interviewer backside also note the physical environment surrounding the interview more than(prenominal) as the respondents office, the house, the dress etc that should tally with his response. race will usually respond with good gesture and provide acc urate responses when approached in person. The Malayan culture of not saying no unperturbed holds true when individual comes to the door with polite and peaceful manner.An experienced interviewer can sense out if the respondent is trying to hide some information. In this case, he will use his creativity to clarify the intention or terminate the interview.Disadvantages of face-to-face interviewHigh cost. Interviewers must be given item preparation on methods overmuch(prenominal) as the art of making personal approach, the art of asking questions, the art of requesting cooperation etc, which is expensive and date consuming. The interviewer must be confident enough to work on his own. At the corresponding date, the daily honorarium for travelling, food, lodging etc is very high.In shade response. Any minor mistake by interviewer can cause error in the response. The mistake such as using a wrong approach, bad facial expression, coming at the wrong time, not sensitive to cert ain(p) issue in the dialogue sometimes could hinder respondents from giving truthful response.Error in disgraceing. This happens particularly when the interview session is in a hurry payable to time constrain on part of respondents. The interviewer who needs to read the question and record the response quickly and simultaneously is prone to making mistakes.Require loaded supervision. The interviewers work should be supervised closely to avoid interviewer cheating. sometimes, due to numerous reasons such as time constraint, respondent is vexed to fall into place or the respondent is not available during appointment time, the interviewer will fill the response on his own.Tele scream interviewSometime it is possible to collect data by mobilize conversation. This method is possible if the researcher has complete directory of band numbers of state under study. If the respondents are government officers, employees of private firm, master key people such as doctors, lawyers, a ccountants etc, then the researcher grow the filling of using this method.Traditional Telephone InterviewIn traditional peal interview, respondents are called through the bring forward and the interviewer will ask a serial of questions and record the responses. Respondents are more willing to provide detailed and unquestionable information on a variety of personal topics over the foretell than with personal interviews.Computer Assisted Telephone Interview (CATI)CATI uses a computing machineized questionnaire administered to respondents over the telephone. The interviewer would tactile sensation respondents over the telephone, read questions posed on the computer screen, and record the respondents answers directly into the computer memory bank. The computer systematically guides the interviewer and checks the responses for appropriateness and consistency.Advantages of telephone interviewLess expensive comparingd to the face-to-face interview. The financial cost for travelli ng, lodging, and outstation requital is not involved.Less time consuming. The number of respondents interviewed through telephone in one day is much higher than the number interviewed through face to face.Easy monitoring. The researcher can monitor the interviewers work more easily since he can check the telephone numbers of respondents and the time called.Disadvantages of telephone interview clinical depressioner response rate. The rate of response is stage out since the respondents can just hang-up the call when he realised it is time consuming, or unsure of the confidentiality of the conversation.Fewer questions could be asked. Usually the conversation through the telephone cannot take long curiously when the topic of discussion is not interesting, especially for the respondent since he has no particular interest in it.Difficult to get good cooperation. Conversation through the phone is not convincing enough especially when trying to get cooperation from the respondent. It i s difficult to bring over someone when they cannot see you in person, your facial expression, you body gesture etc.2) Self-administered questionnaireIn this technique, the researcher distributes questionnaires to respondents personally, through mail service, by inserting in the intelligence activitypapers, or by channelizeing to the email address. The difference between self-administered questionnaires compared to personal interview is in the self-administered questionnaire, the respondents make an effort to read and respond to the questions. However, the effectiveness of self-administered questionnaire will depend on the efficiency of the written words rather than the wanton skill of interviewers.Mail SurveyA mail sentiment is a self-administered questionnaire sent to pre-selected respondents through the mail. Basically, a mail interview package consists of the extraverted envelope, cover garner, questionnaire, return envelope, and possibly an incentive.Mail PanelA mail pane l consists of a large, nationally representative sample of households that choose concur to participate in periodic mail questionnaires and product tests. The data on the panel members is updated every year and households are compensated with various incentives. Mail panel is appropriate for longitudinal design studies which allow obtaining information from the same respondents repeatedly.Advantages of mail report first base cost.No interviewer biasDisadvantages of mail surveyLow response rateSlow data collection hurryingStructured questionnairesOne of the approximately popular methods of collecting research data is through the structured questionnaire. These questionnaires are self-explained and self-administered. In using this method, the researcher designs guardedly a series of questions that cover the variables of interest in the study such as the respondents demographic background, their opinions concerning certain issues, their perception concerning certain service perf ormance, and their intentions to do in the future etc. Structured refers to the degree of standardization enforce in the process of data collection (questionnaires). In other words, the researcher arranges the questions properly on a paper together with the cover letter to explain the purpose of data collection, the instruction to the respondents on how to respond to the questions, and the assurance of confidentiality of information provided.Advantages of a questionnaireLowest cost incurred. The cost is low due to no interview, no training of interviewers, no travelling, no lodging allowance involved.No monitoring cost incurred. Usually the direct of questionnaires and receipt of responses from respondents are done by the researcher himself.More respondents and wider area can be covered. The researchers can sling his questionnaires to as many respondents as he wants since the cost for each respondent is very small.Response more accurate. Since on that point is no influence, no g esture, no facial expression, and no interruption from the interviewer, the respondents can answer the questions at his own convenience. This manner will assure the accuracy of responses.Disadvantages of a questionnaireThe poor rate of response from respondents. Since the researcher does not earn gestures or face-to-face contact with respondents, the respondents can just throw away the questionnaires. In this method, the researcher should make a regular stick with up contact with respondents using letter or telephone call. Usually the researcher would call the respondents earlier to inform them that he is sending a questionnaire to obtain data for his specific objective. The call is made as a gesture in order to obtain good cooperation from respondents.Once the respondent has difficulty regarding certain terms or questions in the questionnaire, he will not annoyance completing the remaining questions since nobody is available to explain. sometimes the respondents simply send back the incomplete response. there is no assurance that the person who responds to the questionnaire is the intend respondent or the legitimate respondent. This matter will result in sample not universe representative of the population.Private agents who conduct surveys give that people are more likely to respond to mail questionnaire that has passkey appearance and come together with attractive prizes such as easily-off draws for the respondents who send the completed questionnaire in time. Some questionnaires obtain good responses from respondents especially the questionnaire that comes together with the warranty cards when customers purchase certain products. Customers will fork out to answer series of questions on the warranty cards before sending back to the manufacturer for product warranty.Computerised questionnaireInternet surveyLately, the internet study has become one of the popular methods to obtain information from the public especially their opinion concerning cert ain issue of public interest. In internet survey, the researcher brings an issue to attention and requests the opinion from the public. The public can respond by voting the statement that closely resembles their opinion. At the same time they can view the current standing in term of the most popular opinion and the corresponding vote obtained.Internet survey appears when a computer user is asked to go to a particular Web site fixing and answer the series of questions displayed in the website. In this technique, the respondents are not selected using specific technique but those who visit the Web site where the survey is posted are invited to participate in the survey.2. E-mail surveyIn the e-mail survey, questionnaires are sent out to the respondents directly through their e-mail address. The respondents would reply the email by providing their response to each item on the questionnaire. The professional market research groups are using the internet to send their questionnaires to the respondents email. The respondents would complete their respective questionnaires and also return through the internet to the researchers e-mail address. Normally, these research agencies would provide certain rewards in terms of discount coupons etc in order to encourage the respondents to participate in the study.Advantages of computerised questionnaireLow cost.Very high data collection speed.Non interviewer biasDisadvantages of computerised questionnaireVery low response rateLow control of data collection methodB) The comment methods consort to Zikmund, Babin, Carr and Griffin (2010), observation is the systematic process of recording the conductal patterns of people, objects and occurrences as they are witnessed. Several types of observation methods areDirect observationIn this method, the researcher will identify his respondents and records the required data based on what he observes. This method is suitable for a research to study the behaviour of respondents. For example , the research is carried out to identify how car drivers behave on the path during profession jam. In his observation, the researcher will record the type of drivers who follow the traffic rules properly, and the type of drivers who choose to ignore rules such as stand jumping or overtaking using emergency lanes. The researcher whitethorn also be concerned to inhabit the types of vehicles (motorcycles, cars, buses, and lorries) which always ignore traffic rules during traffic jams. Another area where this method is suitable is to observe customers behaviour in the supermarket. In the market research study for example, the researcher is interested to inhabit how customers make conclusions in choosing which shampoo to buy. The researcher will stand in the area where hundreds of shampoos of unalike brands are placed on the rack. He will record how the customers choose the shampoo. Most probably some customers have decided earlier which brand to buy some customers will compare p rices, packaging, and until now the smells before buying the shampoo. The researcher will record specific characteristics of customers who pick certain brands of shampoo etc.Advantages of direct observationThe data obtained reflect the bourgeoned behaviour of respondents. The respondents will tend to hide their actual behaviour when approached in person or when answering the questionnaires.The researcher gets a clearer picture and a better feeling of the situations for his study. Hence, he will be in a better position to make a proper recommendation regarding the underlying phenomena in the study.Disadvantages of direct observationThe respondent will not act his normal behaviour if he knows that he is being observed.The data collection process is cumbersome and tedious.Mechanical observationSometimes certain robotic devices such as video cameras, rather than pitying perceivers to observe are used and record customer behaviours. The devices do not require the respondents direct participation in the study but they will capture the respondents behaviour for analysis. The early application of this technique is in a study to determine the level of comfort among train passengers by attach or recording how they sat and moved in their seats.Advantages of mechanical observationIt offers high disguise by using the hidden camera. However, other mechanical device such as the use of psychotic galvanometers is very difficult to disguise.Low observation bias since mechanical observation involves the non-human observer.Disadvantages of mechanical observationLow ability to observe in a natural setting. However, it depends on the mechanical tools used in the observation. The degree is low when using psycho galvanometer but high if using turnstiles.Less flexible.Content analysisContent analysis is usually used to study communication rather than behaviour, or physical objects. It is defined as the objective, systematic, and quantitative description of the manifest capaci tance of a communication. Content analysis obtains data by observing and analyzing the table of contents or messages of advertisements, newspaper articles, television programs, etc.It involves analysis as well as observation which systematically analyze peoples communication to identify the specific information contents and other characteristics such as words, characters (individuals or objects), themes (propositions), quad and time measures (length or duration of the message), or topics (subject of the message).Advantages of content analysisHigh degree of disguise since the data is collected over the situation to be observed.High degree of observation specification and measurement.Disadvantages of content analysisLow ability to observe in natural setting because observation takes place after the behaviour has occurred.Potential of observation bias because human observer is involved in data collection process.5.3 Factors determining choice of survey methods.Selecting the type of su rvey you are going to use is one of the most critical decisions in many social research contexts. Youll see that there are very few simple rules that will make the decision for you you have to use your judgment to balance the advantages and disadvantages of different survey types. There are several factors needs to be consideredPopulation issuesThe archetypical set of considerations has to do with the population and its accessibility.Can the population be specified?For some populations, you have a complete listing of the units that will be sampled. For others, such a list is difficult or impossible to compile. For instance, there are complete listings of registered voters or person with active drivers licenses. But no one keeps a complete list of homeless people. If you are doing a study that requires input from homeless persons, you are very likely going to need to go and find the respondents personally. In such contexts, you can pretty much rule out the idea of mail surveys or t elephone interviews.Is the population literate?Questionnaires require that your respondents can read. While this might depend ab initio like a reasonable assumption for many adult populations, we know from recent research that the instance of adult illiteracy is alarmingly high. And, even if your respondents can read to some degree, your questionnaire whitethorn contain difficult or technical vocabulary. Clearly, there are some populations that you would dwell to be illiterate. younker children would not be good proposes for questionnairesAre there language issues?We pass away in a multilingual world. Virtually every society has members who babble other than the predominant language. Can you produce multiple versions of your questionnaire? For mail promoters, can you know in advance the language your respondent speaks, or do you send multiple translations of your instrument? Can you be confident that important connotations in your instrument are not culturally specific? Coul d some of the important nuances get lost in the process of translating your questions? ordain the population cooperate?People who do research on immigration issues have a difficult methodological problem. They much need to speak with unregistered immigrants or people who whitethorn be able to identify others who are. why would we expect those respondents to cooperate? Although the researcher whitethorn mean no harm, the respondents are at considerable risk legally if information they divulge should get into the hand of the authorities. The same can be said for any target group that is engaging in illegal or unpopular activities.What are the geographic restrictions?Is your population of interest outspread over too large a geographic range for you to study feasibly with a personal interview? It may be possible for you to send a mail instrument to a nationwide sample. You may be able to conduct phone interviews with them. But it will almost certainly be less practicable to do r esearch that requires interviewers to visit directly with respondents if they are widely dispersedSampling issuesThe sample is the actual group you will have to contact in some way. There are several important have issues you need to consider when doing survey research.What data is available?What information do you have about your sample? Do you know their current addresses? Do you have their current phone numbers? Do you have an up to date contact lists?Can these respondents be found?Can your respondents be graded? Some people are very busy. Some travel a lot. Some work the night shift. Even if you have an accurate phone or address, you may not be able to locate or make contact with your sample.Who is the respondent?Who is the respondent in your study? Lets say you draw a sample of households in a small city. A household is not a respondent. Do you want to interview a specific individual? Do you want to talk only to the head of household (and how is that person defined)? Are you willing to talk to any member of the household? Do you state that you will speak to the first adult member of the household who opens the door? What if that person is unwilling to be interviewed but someone else in the house is willing?Can all members of population be sampled?If you have an incomplete list of the population (i.e., ingest frame) you may not be able to sample every member of the population. Lists of various groups are extremely hard to keep up to date. People move or change their names. Even though they are on your sampling frame listing, you may not be able to get to them. And, its possible they are not even on the list.Are response rates likely to be a problem?Even if you are able to solve all of the other population and sampling problems, you still have to deal with the issue of response rates. Some members of your sample will simply refuse to respond. Others have the best of intentions, but cant seem to find the time to send in your questionnaire by the due date. motionless others misplace the instrument or forget about the appointment for an interview. Low response rates are among the most difficult of problems in survey research. They can ruin an otherwise well-designed survey effortQuestion issuesSometimes the nature of what you want to ask respondents will determine the type of survey you select.What types of questions can be asked?Are you going to be asking personal questions? Are you going to need to get lots of detail in the responses? Can you anticipate the most frequent or important types of responses and develop reasonable closed-ended questions?How complex will the questions be?Sometimes you are relations with a complex subject or topic. The questions you want to ask are going to have multiple parts. You may need to branch to sub-questions.Will the screening of questions be needed?A screening question may be needed to determine whether the respondent is qualified to answer your question of interest. For instance, you wouldnt wa nt to ask someone their opinions about a specific computer program without first screening them to find out whether they have any experience using the program. Sometimes you have to screen on several variables (e.g., age, gender, experience). The more complicated the screening, the less likely it is that you can rely on paper-and-pencil instruments without confusing the respondent.Can question place be controlled?Is your survey one where you can construct in advance a reasonable sequence of questions? Or, are you doing an initial exploratory study where you may need to ask lots of follow-up questions that you cant easily anticipate?Will lengthy questions be asked?If your subject matter is complicated, you may need to give the respondent some detailed background for a question. Can you reasonably expect your respondent to sit still long enough in a phone interview to ask your question?Will long response scales be used?If you are asking people about the different computer equipment they use, you may have to have a lengthy response list (CD-ROM drive, floppy drive, mouse, touch pad, modem, network connection, external speakers, etc.). Clearly, it may be difficult to ask about each of these in a nobble phone interview.Content issuesThe content of your study can also pose challenges for the different survey types you might utilize.Can the respondents be expected to know about the issue?If the respondent does not keep up with the news (e.g., by reading the newspaper, watching television news, or talking with others), they may not even know about the news issue you want to ask them about. Or, if you want to do a study of family finances and you are talking to the spouse who doesnt pay the bills on a regular basis, they may not have the information to answer your questions.Will respondent need to consult records?Even if the respondent understands what youre asking about, you may need to allow them to consult their records in order to get an accurate answer. For ins tance, if you ask them how much money they spent on food in the past month, they may need to construe up their personal check and credit card records. In this case, you dont want to be involved in an interview where they would have to go enumerate things up while they keep you waiting (they wouldnt be comfortable with that).Bias issuesPeople come to the research endeavor with their own sets of biases and prejudices. Sometimes, these biases will be less of a problem with certain types of survey approaches.Can social desirability be avoided?Respondents generally want to look good in the eyes of others. None of us likes to look like we dont know an answer. We dont want to say anything that would be embarrassing. If you ask people about information that may put them in this kind of position, they may not tell you the truth, or they may spin the response so that it makes them look better. This may be more of a problem in an interview situation where they are face-to face or on the phon e with a live interviewer.Can interviewer bendion and subversion be controlled?Interviewers may distort an interview as well. They may not ask questions that make them uncomfortable. They may not listen carefully to respondents on topics for which they have strong opinions. They may make the judgment that they already know what the respondent would say to a question based on their prior responses, even though that may not be true.Can false respondents be avoided?With mail surveys it may be difficult to know who actually responded. Did the head of household complete the survey or someone else? Did the CEO actually give the responses or instead pass the task off to a subordinate? Is the person youre speaking with on the phone actually who they say they are? At least with personal interviews, you have a reasonable chance of sharp who you are speaking with. In mail surveys or phone interviews, this may not be the case.vi) Administrative issuesLast, but certainly not least, you have to consider the feasibility of the survey method for your study.costsCost is often the major determining factor in selecting survey type. You might prefer to do personal inter
