  3. 3. WHAT IS RESEARCH?
  4. 4. A research is an organized set of activities to study and develop a model or procedure or technique to find the results of a realistic problem supported by literature and data such that its objective/(s) is/(are) optimized and further make recommendations or interferences for implementations.
  5. 5. DA A system of model, procedures and techniques used to find the results of a research problems is called a Research Methodology. WHAT IS RESEARCH METHODOLOGY

  16. 25. HYPOTHESIS TESTING OF PROPORTIONS <ul><li>Qualitative characteristic </li></ul><ul><li>Statistics of Attributes </li></ul><ul><li>Presence of an attribute-Success </li></ul><ul><li>Absence of an attribute-Failure </li></ul>
  17. 26. Testing the difference between proportion based on sample and the proportion for whole population <ul><li>p - p </li></ul><ul><li>z = </li></ul><ul><li>p*q N-n </li></ul><ul><li>n*N </li></ul>

  21. 30. TEST STATISTIC (z) p - p 0.8529-0.70 z = = p*q N-n 0.70*0.30* 6580000-102 n*N 6580000*102 =3.55
  22. 31. RESULT <ul><li>As H 1 is two sided two tail test is applied for determining the rejection region at 5% level of significance </li></ul><ul><li>Z=1.96 </li></ul><ul><li>Calculated value(3.55) is more than the table value(1.96) so we reject the null hypothesis </li></ul>
  23. 32. <ul><li>There is significant difference between proportion of women using branded cosmetics in the sample and proportion of women using branded cosmetics in the population </li></ul>
  24. 33. Chi-Square Test Research objective Null Hypothesis (H0) : Mumbai women do not use branded cosmetics Alternate Hypothesis (H1) : Mumbai women use branded cosmetics E = 102 / 15 = 6.8

  27. 36. Limitations Of Research
  28. 37. <ul><li>Small population size </li></ul><ul><li>Small sample size </li></ul><ul><li>Only women cosmetics were considered </li></ul><ul><li>Only few brands were considered </li></ul>
