• 1. Unit – 3: Data Collection [Research Methodology, M.Com 3rd Semester]The task of data collection begins after a research problem has been defined and researchdesign/ plan chalked out. While deciding about the method of data collection to be used forthe study, the researcher should keep in mind two types of data viz., primary and secondary.The primary data are those which are collected afresh and for the first time, and thus happento be original in character. The secondary data, on the other hand, are those which havealready been collected by someone else and which have already been passed through thestatistical process. The researcher would have to decide which sort of data he would be using(thus collecting) for his study and accordingly he will have to select one or the other methodof data collection. The methods of collecting primary and secondary data differ since primarydata are to be originally collected, while in case of secondary data the nature of datacollection work is merely that of compilation. We describe the different methods of datacollection, with the pros and cons of each method.COLLECTION OF PRIMARY DATAWe collect primary data during the course of doing experiments in an experimental researchbut in case we do research of the descriptive type and perform surveys, whether samplesurveys or census surveys, then we can obtain primary data either through observation orthrough direct communication with respondents in one form or another or through personalinterviews.* This, in other words, means that there are several methods of collecting primarydata, particularly in surveys and descriptive researches. Important ones are: (i) observationmethod, (ii) interview method, (iii) through questionnaires, (iv) through schedules, and (v)other methods which include (a) warranty cards; (b) distributor audits; (c) pantry audits; (d)consumer panels; (e) using mechanical devices; (f) through projective techniques; (g) depthinterviews, and (h) content analysis.Interview MethodThe interview method of collecting data involves presentation of oral-verbal stimuli and replyin terms of oral-verbal responses. This method can be used through personal interviews and,if possible, through telephone interviews. PERSONAL INTERVIEWSPersonal interview method requires a person known as the interviewer asking questionsgenerally in a face-to-face contact to the other person or persons. (At times the intervieweemay also ask certain questions and the interviewer responds to these, but usually theinterviewer initiates the interview and collects the information.)This sort of interview may be in the form of direct personal investigation or it may be indirectoral investigation. In the case of direct personal investigation the interviewer has to collectthe information personally from the sources concerned. He has to be on the spot and has tomeet people from whom data have to be collected.The method of collecting information through personal interviews is usually carried out in astructured way. As such we call the interviews as structured interviews. Such interviewsinvolve the use of a set of predetermined questions and of highly standardised techniques of Prepared By: Anuj Bhatia [BBA (Gold Medalist), M.Com (Gold Medalist), GSET, UGC NET, Ph.D (Pur.)] 1 Contact: (M) 9898251471 E-mail: anujbhatia09@gmail.com SHAH TUITION CLASSES – Managed by: Nilesh Shah (M. 9825787333)
