Question

There are eight boys in a pre-school class. Their mean height is 33 inches and their median height is 33 inches. The tallest boy whose height is 38 inches moves away and is replaced by a boy whose height is 39 inches. How does this affect the median

Answer 1

Using the median concept, it is found that it would remain the same, as only the tallest student is replaced, which does not influence the median.

What is the median?

The median of a data-set is the value that separates the bottom 50% from the upper 50% of values.

Hence:

• In a data-set of 8 values, the median is the mean between the 4th and the 5th elements.

• Only the tallest student is replaced, which is the 8th element, hence not affecting the median, which remains the same.
