Standard deviation: It is the square root of mean/average of squared deviations of data point from mean i.e. we subtract the mean from each data point; take it's square value (which is again non-negative); sum it up and divide by the number of observations. Surely, standard deviation is a better & most commonly used measure of variation. For more details on the comparison between the two, please see Mean absolute deviation vs. standard deviation 19.5k Views Â· View Upvoters
For the set of test scores, the standard deviation is the square root of 75.76, or 8.7. Remember that standard deviation needs to be interpreted within the context of the data set. If you have 100 items in a data set and the standard deviation is 20, there is a relatively large spread of values away from the mean.
