Sampling krejcie and morgan table. To address the existing gap krejcie morgan 1970 came up with a table for determining sample size for a given population for easy reference. Adapted from krejcie and morgan 1970 3 4 1 exclusion criteria. Sample size estimation using krejcie and morgan and cohen statistical power analysis. The ever increasing need for a representative statistical sample in empirical research has created the demand for an effective method of determining sample size.

The sample size s was determined using the krejcie and morgan table which amounted to one hundred and fifty eight 158 as the sample size s from a population size n of 265 employees chuan. The krejcie and morgan table help the researcher to determine the sample size.
