Measures of dispersion (quartiles, percentiles, ranges) provide information on the spread of the data around the centre. Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean or expected value).A low standard deviation means that most of the numbers are close to the average, while a high standard deviation means that the numbers are more spread out. Se hela listan på mathemania.com When extreme outliers are present, the standard deviation will be considerably larger than the mean absolute deviation. The following example illustrates this point. Example: Mean Absolute Deviation vs.

It is a popular measure of variability because it returns to the original units of measure of the data set. Like the variance, if the data points are close to mean, there is a small variation whereas the data points are highly spread out from the mean, then it has a high variance.
