✓

Answer

A comprehensive way to classify raw data of a quantitative variable is known as a frequency distribution. Class limits are the two ends of a class. The lowest value is called 'lower class limit' and the highest value is called the ‘upper class limit' of a distribution. Class mark refers to class ‘mid-point which is the middle value of a class. It is calculated by the formula given below.$\frac{\text{Class Mark}}{\text{Class Mid-Point}}=\text{Upper limit +}\frac{\text{Lower limit}}{2}$
