Question

Find the mean and median of the data. 8 1/2,6 5/8,3 1/8,5 3/4,6 5/8,5 1/4,10 5/8,4 1/2 The mean is . The median is .

Answer 1

Median = 6.1875

Mean = 6.375

Explanation:

Given the data:

8 1/2,6 5/8,3 1/8,5 3/4,6 5/8,5 1/4,10 5/8,4 1/2

Arranging in ascending order :

3 1/8, 4 1/2, 5 1/4, 5 3/4, 6 5/8, 6 5/8, 8 1/2, 10 5/8

Median = 1/2(n + 1)th term

n = 8

1/2 (9) th term

= 4.5th term

(5 3/4 + 6 5/8) / 2

= 6.1875

Mean = Σx / n

Mean = 51 / 8

Mean = 6.375
