difference between equal-frequency and equal-interval (or -size) class intervals.

In equal-frequency we divide the range [A, B] of the variable into intervals that contain (approximately) equal number of points; equal frequency may not be possible due to repeated

Generally, a histogram will have bars of equal width, although this is not the case when class intervals vary in size. The bars are of equal width and correspond to the equal class intervals, while the height of each bar corresponds to the frequency of the class it represents

In the equal Interval class interval , each class has an equal range of values; that is, the difference between the high and low value is equal for each class. You should use this method if your data is evenly distributed and you want to emphasize the difference in values between the features.

A Histogram shows the frequency of Grouped Data in Class Intervals. The height of each histogram bar is calculated by dividing the frequency by the Class Width. This height is called the Frequency Density. a histogram with equal intervals, the class width is constant.
