R Commander – hypothesis testing

June 16th, 2010

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.
