I have obtained histograms of two different data. Are there any particular features than can be obtained from the histograms to differentiate between the data?? have attached the histograms for reference.

You have two classes just now, with one sample in each. Principal Components Analysis might be the best way to determine the most significant features in your data.

If you’re interested in the probability of your two samples having the same pattern, I suggest the chi-squared test.

The data have to have the same number of bins, so you may have to re-run your program setting the bin numbers of each analysis to be the same.

Hi, i do not want to compare them. I need to extract some features from both histograms and then use those features to differentiate between two classes/data.
