Question

Match the given class interval with their class width.

• A. 10
• B. 20
• C. 5
• D. 50

Answer 1

The difference between the upper class limit and lower class limit is called the width of the class interval.

Upper class limit - Lower class limit = Width
Width of the interval 100-150 = 150 - 100 = 50
Width of the interval 5-10 =10 - 5 = 5
Width of the interval 100-120 =120 - 100 = 20
Width of the interval 0-10 =10 - 0 = 10
