Class 11 Maths Statistics Continuous frequency distribution

Continuous frequency distribution

A continuous frequency distribution is a series in which the data are classified into different class-intervals without gaps along with their respective frequencies.

While calculating the mean of a continuous frequency distribution, we had made the assumption that the frequency in each class is centered at its mid-point. Here also, we write the mid-point of each given class and proceed further as for a discrete frequency distribution to find the mean deviation
