    Use AVERAGE to get the mean, and STEV or STDEVP to get the deviation.

    Re: Calculate one standard deviation from mean

    i was specifically asked to calculate 'one standard deviation' from the mean. i know the std deviation is 0.65 of those 4 numbers, but am not sure if that is my answer or not, and i'm not smart enough to know what exactly that means. Thanks.
