Use more standard charts

What we have looks similar to "Box and whisker plot", see https://www.youtube.com/watch?v=b2C9I8HuCe4
The difference is that in there they have median instead of mean; And also box shows quartiles (medians of lower and upper halves), while we just show STD.
I think their way makes more sense.
First of all, because outliers don't impact the median as much.

Maybe even find outliers (<Q1-1.5xIQR or >Q3+1.5xIQR) and show them as dots instead of including them in the range, like here:
