Since this is a parametric test, an **error plot** is an appropriate presentation of the data and is used in the example report. It shows the mean and variance of the samples being compared and is a clear way of demonstrating the degree of overlap between samples.

As part of the check that data satisfy the parametric criteria, it may be appropriate to plot out the data for each sample as a **histogram** to assess the closeness of the distribution to a normal distribution. This would not apply to small samples.
