CALCULATING STANDARD DEVIATION. The standard deviation is used to tell how far on average any data point is from the mean. The smaller the standard deviation, the closer the scores are on average to the mean. When the standard deviation is large, the scores are more widely spread out on average from the mean.

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.
