Expert Solution
Step 1

Practically the number of classes should neither be too small nor too large. If number of classes is too small then the classification becomes very broad and frequencies will be crowded in a single class. If number of classes is too large then there will be irregular pattern frequencies in different classes thus making the frequency distribution irregular.

There are number of rules for calculating number of classes,. One of the most popular one is

k=1+3.322*log10N=1+3.322*log10500=9.9559≈10
