# Comparing Proportions in R

Previously, we described the essentials of R programming and provided quick start guides for importing data into **R**. Additionally, we described how to compute descriptive or summary statistics, correlation analysis, as well as, how to compare sample means and variances using R software.

This chapter contains articles describing

**statistical tests**to use for**comparing proportions**.# 1 How this chapter is organized?

- One-Proportion Z-Test in R: Compare an Observed Proportion to an Expected One
- Two Proportions Z-Test in R: Compare Two Observed Proportions
- Chi-Square Goodness of Fit Test in R: Compare Multiple Observed Proportions to Expected Probabilities
- Chi-Square Test of Independence in R: Evaluate The Association Between Two Categorical Variables
