What is frequency density? Frequency density is given by the formula; Frequency density is used with grouped data (class intervals) it is particularly useful when the class intervals are of unequal width; it provides a measure of how spread out data within its class interval is, relative to its size; For example,
Frequency density is the frequency per unit for the data in each class. It is calculated by dividing the frequency by the class width ie the difference between the upper limit of the class interval and the lower limit of the class interval. We use frequency density to plot histograms.
The frequency density formula is a calculation that involves dividing the frequency by the class width. We use frequency density to plot histograms which show frequency distribution. The larger the area of the bar on a histogram, the higher the frequency. We can calculate the frequency density by using the formula.
Frequency density. A histogram is drawn like a bar chart, but often has bars of unequal width. It is the area of the bar that tells us the frequency in a histogram, not its height. Key fact....
For a set of grouped data, the frequency density of a class is defined by \[\text{frequency density}=\frac{\text{frequency}}{\text{class width}}.\] It gives the frequency per unit for the data in this class, where the unit is the unit of measurement of the data.
Frequency density tells us the ratio of a frequency of a class to its width. We can calculate frequency density by using the formula that frequency density is equal to frequency over the class width.
One of you asked me to help solving the following exam question involving mode, median and mean. I will also explain to you how to calculate the mean when given a grouped frequency table. Finally you will learn what a histogram is and what is meant with frequency density.

Frequency Density is a concept used to allow the comparison of different categories or classes in a histogram where the class widths are not equal. Frequency density is calculated by dividing the frequency of each class by the width of the class, i.e., Frequency Density = Frequency / Class Width.
