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:
The frequency distribution of this data set looks like this:
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:
