Question

Finding the mode and range of a data setThe nine cats in a pet store were weighed. Their weights (in pounds) are given below.2, 9, 8, 9, 4, 2, 2, 2, 2Find the mode and the range for the data.

Answer 1

Recall that the mode of a set of data is the value that occurs most often. The range is the difference between the largest value and the smallest value in a set of data.

To answer these questions we will use the following frequency chart:

From the above table, we get that the mode of the data set is

`2.`

The largest value of the data set is

`9`

and the smallest value is

`2.`

Therefore, the range is:

`9-2=7.`

Answer:

Mode:

`2.`

Range:

`7.`
