Research methodology

  1. 1. RELEVANCE & SCOPE OF RESEARCH IN MANAGEMENT<br />Definition of Marketing Research: “ Systematic<br />design, collection, record, analysis and reporting of data for aid in making business decisions.”<br /><ul><li>Literally Research means to “search again”. It connotes scientific investigation wherein the researcher takes another, more careful look at the data to discover all that can be known about the subject of study
  2. 2. If information generated or data collected and analyzed are to be accurate, researcher must have an objective, without engaging in a biased attempt to prove preconceived ideas.
  3. 3. Objective is to facilitate the managerial decision making process for all aspect of business: Finance, Marketing, Personal and so on. </li></ul>1<br />suresh<br />

Types:<br /><ul><li> Quota
  88. 88. Judgment/purposive
  89. 89. Convenience
  90. 90. Snowball</li></ul>Technique in which every member of the population has a known, nonzero probability of selection. Types:<br /><ul><li>Simple random
  91. 91. Systematic
  92. 92. Stratified
  93. 93. Cluster</li></li></ul><li>Selection of sample design<br />Probability<br />33<br />suresh<br /><ul><li>Simple random: Each possible sample has an equal probability of being included in the sample. Each member of sample is assigned a number and sample unit is selected by random method. </li></ul> Eg. Random digit dialing for Telephone interviews or random selection of respondents from census data.<br /><ul><li>Systematic: Elements are selected from population at a uniform interval that is measured in time or order. </li></ul> Eg. Mall Intercept PI conducted every Wednesday in Bigbazaar or 2 houses skipped after every door to door interview. <br />
  94. 94. Selection of sample design<br />Probability<br />34<br />suresh<br /><ul><li> Stratified: Population divided into relatively homogeneous group, called strata. From each stratum, a specified no. of elements corresponding to the proportion of that stratum in the population is selected by simple random sampling. Eg. Out of an entire population of 50,000 of an area, if people from age group 20-24 yrs are 10,000, then after a sample of, say 200 is achieved by simple random sampling, the number people between that age group will be more or less 40.
  95. 95. Cluster: Population is divided into groups or cluster. Eg. Survey to be conducted in North and West.</li></ul>*In Stratified, each group has small variation within itself but wide variation between groups. <br /> There is considerable variation within each group but the groups are similar to each other. <br />
  96. 96. Selection of sample design<br />Non Probability<br />35<br />suresh<br /><ul><li> Quota: Various subgroup in a population are represented by sample to the exact extent that the researcher desires. Eg. Out of an entire population of 50,000 of an area, if people from age group 20-24 yrs are 10,000, then </li></ul> a Quota of 40 people should be achieved in that age group if the sample size is selected as 200.<br />Purpose is to ensure various subgroups in a population are represented<br /> by the sample. Quota sampling have a tendency to include people who are<br /> easily found within the Quota (unlike Stratified in which strata are formed<br /> and people are selected by simple random sampling)<br />
  97. 97. Selection of sample design<br />Non Probability<br />36<br />suresh<br /><ul><li>Judgment/purposive : Experienced researcher selects the sample based on his/her judgment about some characteristics required of the sample member. Eg. For a telecom company study, the proportion of people to be studied for a sample of 1000 are:</li></ul>600 (60%) those who presently use company’s sim card<br />250 (25%) those who have never used company’s sim card<br />150 (15%) those who switched after using company’s sim card<br />The above proportion of sample may be less than fully<br />representative of population<br />
  98. 98. Selection of sample design<br />Non Probability<br />37<br />suresh<br /><ul><li>Convenience : Refers to sampling by obtaining people who are most conveniently available. Eg. News reporters present reviews of a movie from people coming out of theatre, who are presumed to reflect public opinion
  99. 99. Snowball : Sampling procedure in which initial respondents are selected by probability method and additional respondents are obtained from information provided by the initial respondents. </li></li></ul><li>Types of question<br />38<br />suresh<br /><ul><li>Open-ended and Closed-ended :</li></ul> What do u like about Surf detergent:<br />Cleaning power<br />Fragrance<br />Dissolve easily<br />Any other (please specify)______________<br /><ul><li> Dichotomous Questions: Two alternatives given to choose </li></ul> Are you a user of Surf detergent?<br />Yes<br />No<br />
