NCERT Exercise Exercise 14.4

The following number of goals was scored by a team in a series of 10 matches:

2, 3, 4, 5, 0, 1, 3, 3, 4, 3

Find the mean, median and mode of these scores.

The number of goals scored by the team is

2, 3, 4, 5, 0, 1, 3, 3, 4, 3

Arranging the number of goals in ascending order,

0, 1, 2, 3, 3, 3, 3, 4, 4, 5

The number of observations is 10, which is an even number. Therefore, median score will be the mean of 10/2 i.e., 5th and 10/2 +1 
i.e., 6th observation while arranged in ascending or descending order.

Mode of data is the observation with the maximum frequency in data.

Therefore, the mode score of data is 3 as it has the maximum frequency as 4 in the data.
