What is the Krejcie & Morgan?

The Krejcie and Morgan table is a statistical tool used to determine sample sizes for surveys and research studies. Developed by William Krejcie and Daryl Morgan in 1970, this table provides a systematic way to calculate how many respondents are needed to ensure that the results are representative of the entire population. It is particularly useful in various fields, including social sciences, marketing research, and public health, where accurate data collection is essential for valid conclusions.

How to use the Krejcie & Morgan

Using the Krejcie and Morgan table involves a few straightforward steps. First, identify the total population size you are studying. Next, locate the corresponding sample size in the table based on your population size and the desired confidence level. The table typically offers sample sizes for different confidence levels, such as ninety-five percent or ninety-nine percent. By following these steps, researchers can ensure they collect sufficient data to support their findings.

Legal use of the Krejcie & Morgan

When using the Krejcie and Morgan table, it is important to understand its legal implications, especially in research settings. The results derived from this table can influence decisions in healthcare, policy-making, and business strategies. Therefore, researchers must ensure that their sampling methods comply with relevant regulations and ethical standards. This includes obtaining informed consent from participants and ensuring confidentiality of collected data.

Steps to complete the Krejcie & Morgan

Completing the Krejcie and Morgan process requires careful planning and execution. Start by defining your research objectives and identifying your target population. Next, calculate the appropriate sample size using the Krejcie and Morgan table. Once you have determined the sample size, develop a survey or data collection instrument. Finally, administer the survey to the selected participants and analyze the data collected to draw conclusions.

Examples of using the Krejcie & Morgan
