Question

What is class width of class 135 – 137, 138 – 140?​

Answer 1

Answer:

Class width = 3

Step-by-step explanation:

Class width is the difference in upper limits or lower limits of 2 consecutive intervals.

Class interval | Lower limit | Upper limit

135 – 137 | 135 | 137

138 – 140 | 138 | 140

Class width = 138 - 135

→ Class width = 3

You can also find out the class limit by taking the difference between the two consecutive upper limits.

Class width = 140 - 137

→ Class width = 3

∴ Class width = 3
