Frequency Distribution
Jakob Jenkov |
A frequency distribution of a data set counts the occurrences of each value in the data set. The number of occurrences of a value is called the frequency of that value. The frequency distributions thus shows how the values in the data set are distributed.
Frequency Distribution Example
Let me show you a frequency distribution example to help illustrate what it looks like. First, here is an example data set:
1,1,1,2,2,3,3,6,6,8,9,9,10
The frequency distribution of this data set looks like this:
| Value | Frequency |
|---|---|
| 1 | 3 |
| 2 | 2 |
| 3 | 2 |
| 6 | 2 |
| 8 | 1 |
| 9 | 2 |
| 10 | 1 |
Visualizing Frequency Distributions With Histograms
You can visualize a frequency distribution with a historgram. Here is a histogram showing the frequency distribution of the example data set:
