Question:

Find the mean of the following frequency distribution:

Scores	5	6	7	8	9
Frequency	2	1	3	2	2

Options:

7.1

7.9

Correct Answer:

7.1

Explanation:

The mean of the following frequency distribution:

Scores	5	6	7	8	9
Frequency	2	1	3	2	2

Total sum = 5 × 2 + 6 × 1 + 7 × 3 + 8 × 2 + 9 × 2 = 71

Total frequency = 2 + 1 + 3 + 2 + 2 = 10

So the mean of the following frequency distribution = 71/10 = 7.1
