A frequency distribution table and chart provide an easy way to present how our data is spread out over a specified range. Through pivot tables, Excel allows us to create a frequency distribution table and chart.
Below is an example of a frequency distribution chart created through pivot tables.

How to create a frequency distribution
Here are the steps to make a frequency distribution:
- Prepare our data
- Insert a pivot table
- Insert a frequency distribution table
- Insert a frequency distribution chart
Prepare our data
Below is a list of names and scores that we want to present as a frequency table and a frequency chart.
Figure 2. Sample data for frequency distribution
Insert pivot table
We insert a pivot table by selecting our data (B2:C12), then clicking Insert tab > PivotTable.
Figure 3. PivotTable option in Insert tab
In the Create PivotTable dialog box:
- Tick Existing Worksheet
- In Location, click the button and select cell E2
This will insert the pivot table in the existing worksheet in cell E2.

How to create a frequency distribution table
- Click anywhere under Row Labels and select Group
Figure 9. Select Group in menu options
The grouping default values will be the minimum and maximum values in our list, and grouping is set by 1.
Figure 10. Default grouping parameters
For this example, we want to group the scores by 5, starting from 75 to 100.
Enter the following in the textboxes:
- Starting at: 75
- Ending at: 100
- By: 5
Figure 11. Customize grouping parameters
Click OK and the frequency distribution table will be created, showing the frequency or count of scores per specific range.

How to create a frequency distribution chart
Click anywhere on the pivot table then click Insert tab > PivotChart
Figure 13. PivotChart in Insert tab
The Insert Chart dialog box will appear. Select the Clustered Column chart type and click OK.
Figure 14. Insert Clustered Column chart
We will instantly create a frequency distribution chart, showing the score ranges in the horizontal axis and the corresponding frequencies in the vertical axis.
Figure 15. Output: Create frequency distribution chart
We can customize our frequency distribution chart by performing the following:
- Change chart title to Scores Frequency Distribution
- Delete the legend
- Format the vertical axis (set maximum value to 5.0, major units to 1.0)
- Change the chart design to Style 8
Finally, we have created a frequency distribution chart, as shown below.
