How is the 'class interval' or 'class width' calculated? |
By adding the lower and upper class limits By subtracting the lower class limit from the upper class limit By multiplying the lower and upper class limits By dividing the upper class limit by the lower class limit |
By subtracting the lower class limit from the upper class limit |
The correct answer is Option 2 : By subtracting the lower class limit from the upper class limit Class Interval or Class Width is the difference between the upper class limit and the lower class limit. For the class 60–70, the class interval is 10 (upper class limit minus lower class limit). |
