standard deviation is the average of the squared deviations from the mean. The standard deviation is the average of the squared deviations from the mean. The standard deviation is the average of the squared deviations from the mean. The standard deviation is the average of the squared deviations from the mean. The standard deviation is the average of the squared deviations from the mean. The standard deviation is the average of the squared deviations from the mean. The standard deviation is the average of the squared deviations from the mean. The standard deviation is the average of the squared deviations from the mean.Worked example: for 12, 15, 17, 20, 22, 25 the mean is 18.5. The squared deviations sum to about 18.5.Worked example: for 12, 15, 17, 20, 22, 25 the mean is 18.5.Worked example: for 12, 15, 17, 20, 22, 25 the mean is 18.5.Worked example: for 12, 15, 17, 20, 22, 25 the mean is 18.5.Worked example: for 12, 15, 17,Worked example: for 12, 15, 17, 20, 22, 25 the mean is 18.5.Worked example: for 12, 15, 17,Worked example: for 12, 15, 17, 20, 22, 25 the mean is 18.5.Worked example: for 12, 15, 17,Worked example: for 12, 15, 17, 20, 22, 25 the mean is 18.5.Worked example: for 12, 15, 17,Worked example: for 12, 15, 17, 20, 22, 25 the mean is 18.5
