Detailed explanation-1: -The frequency of a class interval is the number of observations that occur in a particular predefined interval. So, for example, if 20 people aged 5 to 9 appear in our study’s data, the frequency for the 5–9 interval is 20.

Detailed explanation-2: -A table showing the frequencies of various observations or class intervals of a given data is called a Frequency Distribution table. The upper value of a class interval is called its Upper Class Limit and the lower value of the class interval is called its Lower Class Limit.

Detailed explanation-3: -The class interval with the highest frequency is called the modal class.

Detailed explanation-4: -How can you calculate class interval? Class interval refers to the numerical width of any class in a particular distribution. It is defined as the difference between the upper-class limit and the lower class limit. Class Interval = Upper-Class limit – Lower class limit.
