Abstract

This study aims to develop and evaluate the effectiveness of the “S2Calculator” innovative application for research sample size calculation. The tools used in the study include the “S2Calculator” application and an evaluation form assessing its effectiveness. Data was collected and analyzed using descriptive statistics including mean and standard deviation. The results revealed that the innovative application is capable of the following: 1) explaining the use of sample size calculation formulas, and 2) calculating sample sizes for both known and unknown population sizes. Experts evaluated the application's effectiveness and rated it at the highest level overall. Moreover, the research results indicate that recommended that the application's development should include additional formulas for calculating sample sizes in action and qualitative research, allow users to adjust the font size, and integrate the application for download through AppStore and Google Play to enhance its accessibility.
