Rashid [163]

Answer:

5 classes.

Step-by-step explanation:

You can use the $2^k$ rule to determine the number of classes for a frequency distribution.

The $2^k$ rule says that $2^k\geq n$ where

$k$ is the number of classes

$n$ is the number of the data points

We know that the number of data points is $n$ = 20.

Next, we start searching for $k$ so that we can get a number 2 to the $k$ that is larger that the number of data points.

$2^4=16\\2^5=32$

This suggests that you should use 5 classes.
