No, it's not quite that simple. The mean is the average, the standard deviation is a "standard" measure of the dispersion of values about the mean and the median is the value that splits the set of numbers into two equal halves. Half of people have phantom drain less than the median and the other half, above.

estimate deviation, array range, largest and smallest value in the array, divided by six yields an estimation deviation. Not standard deviation.

it was a tongue in cheek response to, “you know what that is?” Of course I know standard deviation.
