Answer 1

Step-by-step explanation:

Class Interval→One of the ranges into which data in a frequency distribution table are binned.

The ends of a class interval are called class limits, and the middle of an interval is called a class mark.

Answer 2

Answer:

The class mark is the value between the lower and the upper limit of the class. Example - 1-10 is the class then the class mark is 1+10/2 = 5.5.

The class interval is the height of the class ot difference in upper and lower limit.

1 - 10 is the class. class interval = 10 - 1 = 9.
