Question

how to find classes through class mark​

Answer 1

=> First find the difference of the class marks. Then divide the difference by 2. And then subtracted the answer and also add it. You will get class intervals.

For example:-

Class marks are given as 4,8,12.
The difference is 4. Dividing it by 2. we will get 2.
Subtract and add 2 to the class marks. i.e 4-2 and 4+2.
We get class intervals as 2-6.
We can do this further by the same method.

Hope this helps you.
