### Solved Examples

Question 1: Find the Median for the following set of scores:
26, 32, 35, 24, 27, 30, 28, 25, 33, 43.
Solution:

Given data: 24, 25, 26, 27, 28, 30, 32, 33, 35, 43

Here, n = 10 (even)

Median = 29

Question 2: Find the Mean and Median of:
133, 73, 89, 108, 94, 140, 94, 85, 100, 120

Solution:

Given data: 73, 85, 89, 94, 94, 100, 108, 120, 133, 140
(arranged in ascending order)

Mean = 103.6

Median = 97

Question 3: The average score of boys in an examination of a school is 71 and that of the girls is 73. The average score of the school in the examination is 71.8. Find the ratio of the number of boys to the number of girls.

Solution:

Let the number of boys be = x

Let the number of girls be = y

Total score of boys = 71x

Total score of girls = 73y

Total score of all students = 71.8 (x + y)

71.8 (x+y) = 71x + 73y

Therefore the ratio of the number of boys to the number of girls is 3:2.

Question 4: The marks obtained by 102 students in a physics test is given below. Find the average marks.
