Population Krejcie And Morgan Table

This formula is the one used by krejcie morgan in their 1970 article determining sample size for research activities.

Population 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. 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. It was state that this table was use 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.

As for example if the population have 2800 person by referring to the table researcher just need to get a feedback from 338 person. One of the most used method is the krejcie and morgan sampling method. Therefore the population of this study was assumed to have approximately 35 individual. 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.

The krejcie and morgan table help the researcher to determine the sample size. Treat each sub group as a population and then use the table to determine the recommended sample size for each sub group. So the researcher does not need to make the study on each of the sample. The sample size determination.

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. 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. Sample size table from the research. 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.
