Using the table below, find the square of the mode.

Score	4	7	8	11	13	8
Frequency	3	5	2	7	2	1

Worked solution (try it first)

The mode is the score with the highest frequency.
Even with both 8s together ( $2 + 1 = 3$ ), score 11, with frequency 7, is the most common.
So the mode is 11 and its square is $11^2 = 121$ , option D.
