STATISTICS A3

The masses of 8 water melons in kilograms were recorded as follows:

8, 4, 3, 6, 7, 2, 1,  and 1. Calculate the median of these data.

Solution

Arrange the data in order of magnitude starting with the smallest.

1, 1, 2, 3, 4, 6, 7, 8

There are eight data so far. We get the two data in the middle which are 3 and 4.

Median can be calculated by finding the average of the two middle values.

so, median  = 3 + 4

                        2

                      = 3.5

Hence median is 3.5.
