Standard deviation in Excel: functions and formula examples
Standard Deviation. The Standard Deviation is the square root of the variance. You can calculate it with the formula =sqrt(var(range)) or by using the appropriate function, either. stdev(range)or stdevp(range). Because of problems associated with Excel’s method of computing the standard deviation, we will usually calculate it by hand.
