**Software for Exploratory Data Analysis and Statistical Modelling**, and kindly contributed to R-bloggers)The R Commander GUI can be used to perform classical hypothesis testing. There are menu options to undertake the variants on the t-test as well as tests on proportions or equality of variances for two samples of data.

The **“Statistics”** menu provides access to various hypothesis tests via the **“Means”** sub-menu including:

- Single sample t-test – for situations where there is one sample of data and we are testing against hypothesised average for the population.
- Independent two sample t-test – where there are two samples and we are comparing the average values for each sample to look for evidence that the averages are different.
- Paired t-test – the situation where each individual in the sample has two directly comparable measurements.

Other useful resources are provided on the Supplementary Material page.
