Krejcie And Morgan Formula For Sample Size
The sample size representative of the farmers in this study is 32.
Krejcie and morgan formula for sample size. Based on krejcie and morgan s 1970 table for determining sample size for a given population of 500 a sample size of 217 would be needed to represent a crosssection of the population. Sample size estimation using krejcie and morgan and cohen statistical power analysis. Determining sample size for research activities. To simplify the process of determining the sample size for a finite population krejcie morgan 1970 came up with a table using sample size formula for finite population.
Krejcie and morgan s 1970 developed the formulas for determining the sample size for categorical types of data. The sample size determination table 3 0 is derivative from the sample size calculation which expressed as below. It is determine based on the krejcie and morgan s sample size calculation which same as using the krejcie and morgan s sample size determination table. Another developed mode of determining the sample size for the categorical type of data is that of krejcie and morgan s 1970.
For the determination of sample size these formulas provide identical sample sizes in instances where the researcher modified the charted or tabulated value established on the size of the population which should be below or equivalent to 120. Krejcie morgan formula for sample size calculation the ever increasing need for a representative statistical sample in empirical research has created the dema. However it is important for a researcher to consider whether the sample size is adequate to provide enough accuracy to base decisions on the findings with confidence. Sample size table from the research advisors.
To address the existing gap krejcie morgan 1970 came up with a table for determining sample size for a given population for easy reference. These formulas for determining the sample size provide identical sample sizes in cases where the researcher adjusts the tabulated value based on the size of the population which should be less than or equal to 120. One of the most used method is the krejcie and morgan sampling method.
