Can chess.com provided us with a frequency distribution of the ratings of the member e.g. how many 1001-1100, how many 1101-1200, how many 1201-1300?

Even better would be a histogram so we can see the distribution. E.g. is it a normal distribution and if so what is the mean and standard deviation?

The mean is the sum of all values in the sample divided by the number of values in the sample and the standard deviation is calculated as the square root of the variance.
