Question

if a class mark is 10 and class width is 6 then find the class
​

Answer 1

Answer:

it can be any class grade 1,2,3,4,5,6,7,8 and 9

Answer 2

Answer:

We have, class mark = 10 and class width = 6.

Since, 6/2=3

The lower class limit = 10−3=7 and the upper class limit = 10+3=13.

So, the class is 7-13.
