Find out the mode of the following marks obtained by 15 students in a class:
Marks : 4, 6, 5, 7, 9, 8, 10, 4, 7, 6, 5, 9, 8, 7, 7.
Given:
Marks obtained by 15 students in a class are:
Marks : 4, 6, 5, 7, 9, 8, 10, 4, 7, 6, 5, 9, 8, 7, 7.
To do:
We have to find the mode.
Solution:
Arranging the given data in ascending order, we get,
$4, 4, 5, 5, 6, 6, 7, 7, 7, 7, 8, 8, 9, 9, 10$
Here, $7$ occurs maximum times(4)
Therefore,
Mode $= 7$ marks
