The number of goals scored by a football team in 20 matches is shown below. What are the mean and the mode respectively?

No. of goals	0	1	2	3	4	5
No. of matches	3	5	7	4	1	0

Worked solution (try it first)

Total goals: $0(3) + 1(5) + 2(7) + 3(4) + 4(1) + 5(0) = 0 + 5 + 14 + 12 + 4$ , which is 35.
Mean $= \frac{35}{20} = 1.75$ .
The mode is the number of goals with the highest frequency: 2 goals, in 7 matches.
So the mean and mode are $(1.75, 2)$ , option B.
