The histogram can be used only when :
(A) Class intervals are equal or unequal
A histogram is used to represent data usually when the data size is large(greater than 100). The frequency in a histogram is represented by the area of the rectangular bars.
The major difference between a histogram and a bar graph is that histogram does not have spaces in between them and the class interval can be both equal or unequal.
The frequency distribution of the data in a histogram can have both equal and unequal class intervals as the frequency is represented by the area therefore a histogram can represent both types of data.
