How Do You Calculate Standard Deviation? To find the standard deviation: First, see whether the data values represent the population or sample. If they represent the sample, then use the sample standard deviation formula √ [ 1/(n-1) ∑(xi - sample mean)2. If they represent the population...
Pooled Standard Deviation: How Do You Calculate It? Published: September 26, 2024 by Ken Feldman Key Points Pooled standard deviation is an average of averages. You’d use it when comparing standard deviations between multiple data sets. Larger sample sizes can skew results. When you ha...

Suppose you're given the data set 1, 2, 2, 4, 6. Work through each of the steps to find the standard deviation. Calculate the mean of your data set. The mean of the data is (1+2+2+4+6)/5 = 15/5 = 3. Subtract the mean from each of the data values and list the differen...
Calculate the deviation from the mean. The deviation must be calculated separately for each value in the data set. Take the difference between the mean average and each individual value, then take the absolute value of that number. Example: from the above data set, the deviation of the first...
