Question

What is the class size of each class interval? please ans fast​

Answer 1

Answer:

The frequency of a class interval is the number of data values that fall in the range specified by the interval. The size of the class interval is often selected as 5, 10, 15 or 20 etc. Each class interval starts at a value that is a multiple of the size.

Answer 2

Step-by-step explanation:

Class intervals (lengths) should be equal. Intervals such as 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, etc are desirable. The starting point for each class should be divisible by the interval, For example, in the class 15 - 20, the starting point, 15, is divisible by the interval,
