Question

Define frequency density?​

Answer 1

Answer:

It is the area of the bar that tells us the frequency in a histogram, not its height. Instead of plotting frequency on the y-axis, we plot the frequency density. To calculate this, you divide the frequency of a group by the width of it.

Answer 2

For a set of grouped data, the frequency density of a class is defined by

For a set of grouped data, the frequency density of a class is defined byfrequency density=frequencyclass width.

For a set of grouped data, the frequency density of a class is defined byfrequency density=frequencyclass width.It gives the frequency per unit for the data in this class, where the unit is the unit of measurement of the data. This allows for a meaningful comparison of different classes where the class widths may not be equal.

This is the relative frequency of the item divided by its class width, or alternatively, the frequency density divided by the total number of data items:
