# Calculating Cumulative Frequency in Excel (2023)

#### Introduction

Cumulative frequency is a useful statistical measure in the business sector for various reasons. By calculating cumulative frequency, you can see how many observations fall within a given range of values. This information can be helpful for various tasks, like finding outliers, comparing datasets, and predicting future trends based on previous trends. In this article, we will show you two ways to calculate cumulative frequency in Excel.

#### What is Cumulative Frequency?

Cumulative frequency is a statistical term that refers to the total number of times a value or a range of values occur up to a certain point in a frequency distribution, including all values that come before it. In other words, it is the running total of the frequencies of all the values up to a certain point in a frequency distribution.

For example, let's say we have a data set with values of 3, 5, 7, 8, and 10, and their corresponding frequencies are 2, 3, 1, 4, and 2. The cumulative frequency of the value 8 would be the sum of the frequencies of all the values that come before it, which is 2 + 3 + 1 + 4 = 10.

#### Cumulative Frequency Formula

The formula for cumulative frequency is: Cumulative Frequency = Sum of all frequencies up to and including the current frequency

Mathematically, it can be expressed as: CF(i) = ∑f(j) where j = 1 to i

• CF(i) is the cumulative frequency for the i-th observation.
• f(j) is the frequency of the j-th observation.
• The summation (∑) is taken over all observations up to and including the i-th observation.

#### Easiest Way to Calculate Cumulative Frequency in Excel

To calculate cumulative frequency in Excel, you can use the PivotTable feature. Here are the steps:

1. Select the cell range containing your data.
2. Go to the "Insert" tab and select "PivotTable" from the "Tables" group.
3. In the PivotTable dialog box, select "Existing Worksheet" and choose a location for the PivotTable.
4. In the PivotTable Field Task Pane, drag the column containing the values you want to calculate the cumulative frequency for to the "Values" area.
5. Right-click on the header of the column in the PivotTable and select "Value Field Settings".
6. In the "Value Field Settings" dialog box, enter a name for the column and select "Running Total In" from the "Show Values As" drop-down menu.
7. Click "OK" to calculate the cumulative frequency.

#### Additional Steps: Calculate Cumulative Frequency Percentage

If you need to calculate the cumulative frequency percentage, follow these steps:

1. Add a new column beside the existing dataset.
2. In the first cell of the new column, enter the formula "= E2 / \$E\$7" (assuming the cumulative frequency is in column E and the total transaction amount is in cell E7).
3. Copy the formula to the rest of the cells in the column.
4. Format the cells as percentages.

#### Alternative Way: Using Simple Formula to Calculate Cumulative Frequency in Excel

If you prefer to use a simple formula to calculate cumulative frequency, follow these steps:

1. Create a new column beside the dataset.
2. Sort the dataset in ascending order.
3. In the first cell of the new column, enter the value from the corresponding cell in the dataset.
4. In the second cell of the new column, enter the formula "= B3 + C2" (assuming the dataset is in column B and the new column is in column C).
5. Copy the formula to the rest of the cells in the column.

#### Conclusion

In this article, we have discussed the concept of cumulative frequency and provided two methods to calculate it in Excel. The easiest way is to use the PivotTable feature, which allows you to calculate the cumulative frequency with just a few clicks. Alternatively, you can use a simple formula to calculate the cumulative frequency. Both methods provide accurate results and can be used based on your preference and the complexity of your dataset.
