why would the interquartile range be a better measure of spread than the whole range from a box plot diagram? :)

It gives you a better average than using all of the figures, in case of any anomolies.

It doesn't take into consideration extremes in the data so it focuses on the usual trend rather than really low or really high anomalies.

it allows you to find more likely averages from less numbers rather than with anomolous results included
