Sometimes it would be useful to compare results from different data sets.

A typical example would be to compare the diversity (Simpson's Index of Diversity) in data before and after a vaccine is introduced. This might also be specially useful to compare one's data set with published data.

This calculation assumes a normal distribution for both data sets. When the sample sizes are small, they should at least be similar between them.

To more information about how this p-value is calculated, please refer to the tutorial.

This is a rather simple estimation and all you have to do is to input the two confidence intervals from the data sets you want to compare.
