Comparing Variances 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 using R software.


This chapter contains articles describing statistical tests to use for comparing variances.
