Sometimes it is possible to obtain sufficiently accurate results by studying a part/a segment of the population. Thus the few items are selected from the population in such a way that they are the representative of the universe and these representatives in research are called as ‘sample’. The process of selecting the representatives from the population is called ‘sampling’. Thus sampling is simply the process of learning about population on the basis of sample drawn from it. Under this method a small group of universe is taken as the representative of the whole mass and the results are drawn. It is the method to make social/business investigation practicable and easy. Sampling is, therefore, resorted to when either it is impossible to enumerate all the units in the whole population or when it is too costly to enumerate in terms of time and money or when the uncertainty inherent in sampling Continue reading

Social Research – Definition, Steps and Objectives
Definitions of Social Research The term ‘social research’ has been defined by different scholars differently. The few definitions are as follows: Prof. C.A. Moser defined it as “systematized investigation to give new knowledge about social phenomena and surveys, we call social research”. Rummel defined it as “it is devoted to a study to mankind in his social environment and is concerned with improving his understanding of social orders, groups, institutes and ethics”. M.H. Gopal defined it as “it is scientific analysis of the nature and trends of social phenomena of groups or in general of human behavior so as to formulate broad principles and scientific concepts”. Mary Stevenson defined it as “social research is a systematic method of exploring, analyzing and conceptualizing social life in order to extend, correct or verify knowledge, whether that knowledge aid in the construction of a theory or in the practice of an art.

Systematic Random Sampling in Research
In cluster sampling the population again is subdivided into subgroups termed clusters instead of strata. The term cluster means a bunch of similar things. Suppose the thousand employees of a factory in our example comprise of teams each consisting of one supervisor and nine workers, and we choose these teams at random, it is a cluster sample, because we have taken one hundred clusters as our sample. One popular type of cluster sample is the systematic random sample also called quasi-random sample. Suppose the thousand employees of the factory are listed alphabetically and numbered serially to form the sample frame. (The alphabetical order is usually a random arrangement with respect to most characteristics and so forms an unbiased sample frame). As twenty employees are to be chosen from the thousand, it is a one in fifty sample. So, here, 50 is the sampling interval or ‘skip factor’. Now choose a Continue reading
Schedule as a Data Collection Technique in Research
Schedule is the tool or instrument used to collect data from the respondents while interview is conducted. Schedule contains questions, statements (on which opinions are elicited) and blank spaces/tables for filling up the respondents. The features of schedules are : The schedule is presented by the interviewer. The questions are asked and the answers are noted down by him. The list of questions is a more formal document, it need not be attractive. The schedule can be used in a very narrow sphere of social research. The main purposes of schedule are three fold : To provide a standardized tool for observation or interview in order to attain objectivity, To act as memory tickler i.e., the schedule keeps the memory of the interviewer/ observer refreshed and keeps him reminded of the different aspects that are to be particularly observed, and To facilitate the work of tabulation and analysis. Types Continue reading
Guide to the Development of Research Questionnaires
The process of questionnaire development is divided into three phases, (1) Designing or making (2) Issuing (3) Returning. While designing a research questionnaire, attention should be paid to three important matters; Appearance of the questionnaire, Contents of questionnaire, and Subject-matter. Design of Questionnaire To design a good research questionnaire certain steps are needed. These are : Consult colleagues, friends & acquaintances to get their thinking on the problem. Formulation of such a list of areas and questions. Submit this list to experts both in the field of problem and related fields. Drafting the questionnaire (first stage). Pre-testing the questionnaire. Re-examination and revising the questionnaire (second stage). Physical Appearance of the Questionnaire Special attention should be paid in order to give a good physical appearance to the research questionnaire so as to get good response from the respondent. Matters requiring special attention include quality and size of paper, type of Continue reading
In-Depth Interviewing Techniques
In-depth interview is an intensive and searching interview aiming at studying the respondent’s opinion, emotions or convictions on the basis of an interview guide. Conducting an in-depth interview requires much more training on inter-personal skills than structured interview. This deliberately aims to elicit unconscious as well as extremely personal feelings and emotions. In-depth interview is generally a lengthy procedure designed to encourage free expression of affectively charged information. It requires probing. The interviewer should totally avoid advising or showing disagreement. Of course, he should use encouraging expressions like “uh-huh” or “I see” to motivate the respondent to continue narration. Some times the interviewer has to face the problem of affections, i.e. the respondent may hide expressing affective feelings. The interviewer should handle such situation with great care. Many researchers don’t know how to conduct an in-depth interview well. Here are some tips for conducting more effective in-depth interviews. Start the Continue reading
