PS: Power and Sample Size Calculation has the advantage of accommodating six distinct research designs (survival, t-test, regression 1, regression 2, dichotomous, and the Mantel-Haenszel). This program can determine the sample size needed to detect a specific alternative hypothesis at a desired level of significance, the level of significance with which that alternative hypothesis can be detected with a given sample size, or the list of alternative hypotheses that can be tested with that power and sample size.

Specifically, it is an online tool for estimating effect sizes. Its purpose is to make calculating effect sizes for meta-analysis easier. The standardized mean difference, correlation coefficient, odds-ratio, and risk-ratio are the four forms of effect-size that may be calculated using a variety of input data.

A lightweight program like Effect Size Calculator shouldn’t have any noticeable impact on system resources, and that’s exactly what happened here. Information was quickly calculated and displayed, and only a little amount of memory and processing power was required. Unfortunately, there are no data storage export options available. However, it provides a straightforward method for conducting statistical analysis.
