A child says that the median of 3, 14, 18, 20, 5 is 18. What doesn’t the child understand about finding the median?

Solution:

We know that

Median represents the middle value for any group. It is the point at which half the data is more and half the data is less.

Median helps to represent a large number of data points with a single data point. The median is the easiest statistical measure to calculate.

For calculation of median, the data has to be arranged in ascending order, and then the middlemost data point represents the median of the data.

It is given that the median of 3, 14, 18, 20, 5 is 18

While calculating the median, the data has to be arranged in ascending order.

The given data here is not arranged in ascending order by the child.

Therefore, the child does not understand that data has to be arranged in ascending order.
