Question

What measure of variability would be best to describe this distribution?
A.
range
B.
median
C.
mean
D.
interquartile range

Answer 1

D. Interquartile range

The interquartile range would be best to describe this distribution as it provides a measure of variability that is less affected by outliers. It gives a sense of the spread of the middle 50% of the data, which can be more informative in this case compared to the range, median, or mean.
