# Examples See what you can do with Analyse-it

Below are examples of all kinds of analyses using Analyse-it.

You can use them as templates to get started with your own analyses: each includes a dataset so you can see an example of how to arrange your data, and the analyses can be edited (if you have the appropriate edition of Analyse-it) so you can see how they are set-up.

The examples require Analyse-it version 4.80 or later.
