Two sets of data are each symmetrical and do not contain outliers. Which measures of center and variability would be most effective to use when making comparisons between the two data sets?

mean and MAD

mean and IQR

median and MAD

median and IQR

The measure of center that would best represent the data is the mean.

The best measure of variability would be the mean absolute deviation (MAD).

Both of these measures are best because when the data is distributed the same way in both directions (symetric), evening out the data by finding the average (mean) or the MAD is best.
