This repository contains an R script designed to calculate the required sample size for conducting Fisher’s Exact Test for two proportions. The script leverages pilot study data to determine the effect size and then performs a power analysis to estimate the necessary sample size to achieve a specified power and significance level.
- Fisher’s Exact Test: Conducts Fisher’s Exact Test on pilot study data.
- Effect Size Calculation: Computes the effect size based on proportions from pilot studies.
- Power Analysis: Determines the sample size needed for specified power and significance levels.
- Output: Saves power analysis results and session information to text files.
- R: Ensure you have R installed on your system. You can download it from CRAN.
- pwr package: This package is required for power analysis. You can install it using the instructions below.
To install the required pwr package, run the following command in your R console:
install.packages("pwr")
