Find the mode of the following data in each case:

7, 9, 12, 13, 7, 12, 15, 7, 12, 7, 25, 18, 7

Given:

7, 9, 12, 13, 7, 12, 15, 7, 12, 7, 25, 18, 7

To do:

We have to find the mode.

Solution:

Arranging the given data in ascending order, we get,

$7, 7, 7, 7, 7, 9, 12, 12, 12, 13, 15, 18, 25$

Here, $7$ occurs maximum times(5)

Therefore,

Mode $= 7$
