Quizplus · Accepted Answer

The width of a class in a frequency distribution is known as the class interval. This is the range of values that a class represents. For example, if the class is "20-29", the class interval is 10 because it represents all values from 20 to 29 (inclusive). The other options are not correct definitions of class width.
