How to Estimate Standard Deviations (SD) - ThoughtCo Jul 14, 2019 · These values have a mean of 17 and a standard deviation of about 4.1. If instead we first calculate the range of our data as 25 – 12 = 13 and then divide this number by four we have our estimate of the standard deviation as 13/4 = 3.25. This number is relatively close to the true standard deviation and good for a rough estimate.
