I really like how you simplified the variance equation:
going from: \frac{1}{m}\sum_{j = 1}^{m}{x_j} to \bar{x} which make it so much more readable.
I was curious if there was a reason for applying the opposite change for the equation of standard deviation ?
Concerning th info block, the addition to the percentile is great, now linear interpolation is clearly asked for, great !

i don't understand the (m - 1) in the first formula you changed, after the last '=' on top of the sigma. |
