I used my app https://app.prettygraph.com https://app.prettygraph.com to quickly look at the histograms. B and F look almost identical with a very normal distribution. The others look more like twin-peaks. Edit: If you want to try, copy the data and click the "Paste data from Excel link" on the left under the Data Tab, paste and load. Then choose histogram under the Graph tab. It plots the X var (ignores Y). Sorry it's a bit shabby, I haven't worked on it in a while.
