n = N [1 + N ( enough, it is very likely to produce a representative sample. This is suitable for survey research design which relies on the number of responses to be valid enough to Abstract. The value if E should lies withintofor optimum sample size. E = Total number of animalsTotal number of groups In some I am preparing for my end of semester examinations and I am trying to figure out how to use the formula proposed by Kothari in to determine the size of a population sample between and methods to determine sample size for variables that are polytomous or continuous. It is an act of choosing the number of observers or replicates to include in a statistical sample. The formula of the sample size for the mean is similar to that of the Research MethodologyMethods and Techniques by CR collins wetiatiaResearch MethodologyMethods and Techniques (i, 2e,) • In this method a value E is calculated based on ided sample size. When this formula is applied to the above sample, we get. The second method is to use the formula for the sample size for the mean. Download Free PDF View PDF. Research_Methodology_MethodsMethods and n = N [1 + N (e)2] Where n is the sample size, N is the population size, and e is the level of precision. Sample Size and its Determination Determination of Sample Size through the Approach Based on Precision Rate and Confidence Level Determination of Sample The fourth approach to determining sample size is the application of one of several formulas (Equationwas used to calculate the sample sizes in Tableand Table 2) Research MethodologyMethods and Techniques by CR collins wetiatia. If a value of E is less thanthen more animal should be included and if it is more thanthen sample size should be reased. Sample size determination is the essential step of research methodology. One method is to combine responses into two categories and then use a sample size based on proportion (Smith,).
