I have data that goes from negative to positive. When plotted in an histogram it looks like this
The data is the "error".
If I have another set of data I want to learn how to judge which data is "better" (the smaller the error the better the data).
I have been advised to convert everything from frequency to density to standardize the plots and be able to compare. How can I do this?
And what other plots I can use to judge data in this case?
I am trying box plots and I get something like
which has a lot of outliers; eliminating those
I suppose that I can compare somehow these with boxplots of other data, but I am not really sure how.
Any other ideas how to compare and evaluate data are welcomed.
