I am new to statistics, and have a fairly basic question. I have two sets of data that I want to compare with a third dataset. I am only interested in comparing the means and variances.
Turns out that the mean of dataset3 is close to that of dataset1. However, when it comes to variances, dataset2 and dataset3 show close agreement. So, I am not sure which dataset is actually similar to dataset3.
So, I would like to simultaneously compare means and variances. Is there a single metric using which I can compare both together? I am not aware of the distribution of both datasets.
Any help or hints would be greatly appreciated.
