Answer 1

Let us revise how to find the median

At first you must arrange the numbers from small to big

Let us do that

14, 18, 20, 22, 24, 24

We have 6 numbers we need to find the middle one because the median means middle number in a set of data

But there are 6 numbers the middle numbers are 20 and 22

So the median will be the average of the two number

$\text{Median}=\frac{20+22}{2}=\frac{42}{2}=21$

There is a very important note for the median

If the number of data is even the median will be the average of the middle two numbers as our question, but if the number of data is odd then the median will be the middle number.

The answer is the first choice
