Krejcie And Morgan Sample Size Table
So the researcher does not need to make the study on each of the sample.
Krejcie and morgan sample size table. 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. Krejcie morgan formula for sample size calculation the ever increasing need for a representative statistical sample in empirical research has created the dema. As for example if the population have 2800 person by referring to the table researcher just need to get a feedback from 338 person. The krejcie and morgan table help the researcher to determine the sample size.
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. This formula is the one used by krejcie morgan in their 1970 article determining sample size for research activities educational and psychological measurement 30 pp. One of the most used method is the krejcie and morgan sampling method. 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 table is applicable to any population of a defined finite size. Krejcie and morgan 1970 have produced a table for determining required sample size given a finite population. Sample size estimation using krejcie and morgan and cohen statistical power analysis.
