If the sample size is too small, even a well conducted study may fail to detect important effects or associations, or may estimate those impacts or associations too imprecisely. Roscoe (1975) suggested that sample sizes larger than 30 and less than 500 are appropriate for most research. 0000000935 00000 n 0000002695 00000 n endobj 0000187176 00000 n 0000192603 00000 n According to Denzin and Lincoln (2005) a research methodology or strategy is determined by the nature of the research question and the subject being investigated.

It provides information concerning the method that was used in undertaking this research as well as a justification for the use of this method. <> Sample selection depends on the population size, its homogeneity, the sample media and its cost of use, and the degree of precision required (Salant & Dillman, 1994, p. 54). This book is useful those students who offer the Research Methodology at Post Graduation and M.Phil. The sample size of a survey most typically refers to the number of units that were chosen from which data were gathered. 3 0 obj 0000187477 00000 n x��ZKo�8����Z�i�� �c��[email protected]�v�{���ӱ0��d��~�HJV"��3�l��zP�������M����#�^��t]~�Uk���������W�O�mQ�]QW�χ�/�]�kռ~M޾G�^^�4Ŀ4M ��$���'������Huy����b�#��0"W��FNC�$�)'W;��sBn[����Ԟ}���cA�?��?./~� ���a`,���wd��m�u��m�/u�=��f��2�����Z#�UT��/��h�+�5or�2Lps�2O��SO"����i�\�>�c��V�L�|Fr�R.
