STATISTICS A8

The masses of 10 cabbages in kilograms were recorded as follows:

5, 8, 4, 3, 6, 7, 2, 5, 1 and 9. Calculate the median of these data.

Solution

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

1, 2, 3, 4, 5 ,5,  6, 7, 8, 9

There are eight data so far. We get the two data in the middle which are 5 and 5.

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

So, median  = 5+ 5

                           2

                      = 5

Hence median is 5.
