Question

What will be the class mark of the class interval2.4-6.6?
please give an explanation that how did you solve so that it would be easy for me to understand

Answer 1

Answer:

4.5 is the answer

2.4+6.6/2=9/2=4.5

Classmark: Mid-value of each class interval is called its class mark.

Classsize: Difference between the true upper limit and true lower limit of a class interval is called the class size.

⇒ Class Mark=

Upper limit+Lower limit / 2

⇒ Classsize=Upperlimit−Lowerlimit

I hope it helps:)
