AND UR QUESTION IS ABOUT MEDIAN CLASS WE WILL TAKE THE MEDIAN CLASS OF THAT NO . WHICH IS HIGHEST AMONG THE OTHER FREQUENCY NO.

Answer 2

Let me first tell you what a Median is, so you will be able to understand the concept more clearly.

Median is a mesaure of central tendency which gives the value of the middle most observation in the data.

Now, the reason :

In the question, it is already given that the Median is 28.5.

So the Median Class will be that class in which the Median lies.

Here, the Median Class is 20-30 , since 28.5 lies between 20 and 30.

If you are not able to understand it, please read it twice or thrice. You will be able to understand the concept.
