Question

40 students of class 7 wrote their number of family members together. This number is shown below :

4, 3, 5, 4, 7, 3, 5, 6, 4, 4, 4, 7, 6, 4, 5, 4, 3, 4, 5,
6, 7, 4, 4, 5, 3, 4, 6, 4, 5, 5, 4, 3, 4, 7, 6, 4, 3, 5, 4,

Find out the mode of these observations.

Answer 1

Arranging these observations in ascending orders.

3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4,
4, 4, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5, 6, 6, 6, 6, 6, 7, 7, 7, 7

In the given observations 4 occurs more times, therefore mode is 4.
