The ages (in years) of 10 teachers in a school are:
32, 44, 53, 47, 37, 54, 34, 36, 40, 50.

Find the median age.

By arranging the ages of teachers in ascending order

32, 34, 36, 37, 40, 44, 47, 50, 53, 54

We have;

N = 10 (even number)

Median =

Median age= 42 years

The heights (in cm) of 9 girls are:

144.2, 148.5, 143.7, 149.6, 150, 146.5, 145, 147.3, 152.1.

Find the median height.

The weights (in kg) of 8 children are:

13.4, 10.6, 12.7, 17.2, 14.3, 15, 16.5, 9.8.

Find the median weight.

If 10, 13, 15, 18, x + 1, x + 3, 30, 32, 35, 41 are ten observations in an ascending order with median 24, find the value of x.
