Frequency Density Formula
The following equation is used to calculate the Frequency Density.
FD = F / CW
- Where FD is the frequency density
- F is the frequency
- CW is the class width
What is a Frequency Density?
A frequency density is a measure of the ratio of the frequency of data to the class width of the same data.
How to Calculate Frequency Density?
The following example outlines the steps and information needed to calculate Frequency Density.
First, determine the frequency. In this example, the frequency is found to be 45.
Next, determine the class width. The class width for this example is found to be 20.
Finally, calculate the frequency density using the formula above:
FD = 45/ 20
FD = 45 / 20
