Stat Assistance’s sample size calculator allows users to calculate sample sizes needed for research and survey studies quickly, reliably, and easily without having to search the web for a sample size calculator or calculate sample size needed for research by hand.

Why do you need to compute a sample size? In research it is very difficult to survey an entire population of people. Therefore, researchers use a sample size or sample population to measure the attitudes, beliefs, and practices of a given population. A sample size calculator is used to determine how many people you will need to interview or survey in order to collect enough information so that your results are representative of your target population. This technique is used by researchers to ensure that your research has power and is reliable.

This first of its kind app was developed by a Ph.D. level researcher who has published in academic journals and who serves as an editor of academic journals. This app was created to help researchers determine a sample population that produces reliable results relevant to the population they are looking to research.
