# How to Find Cumulative Frequency in Excel (2023)

In the world of data analytics, cumulative frequency is an important concept that helps us understand how many values are under or above a certain class interval. Whether you're working with scattered data sets or analyzing product-related data in a business area, knowing how to find cumulative frequency in Excel can be incredibly useful. In this article, we will explore two methods for calculating cumulative frequency in Excel: the "Less Than" method and the "More Than" method.

#### How to Find Cumulative Frequency in Excel (Less Than Method)

The "Less Than" method is used to calculate cumulative frequency when you want to find the number of values that are less than or equal to a certain class interval. Let's say we have a table of products and their corresponding frequencies:

Product Frequency
A 21
B 37
C 32
D 19
E 8

To calculate the cumulative frequency using the "Less Than" method, follow these steps:

1. Select the cell where you want to insert the cumulative frequency for the first row. For example, select cell C5.
2. Insert the formula "=B5" in the selected cell. This formula simply copies the frequency value from the corresponding row.
3. For the second row and onwards, use the formula "=B6+C5". This formula adds the frequency value of the current row to the cumulative frequency of the previous row.
4. Copy the formula down the column to calculate the cumulative frequency for the remaining rows.

After following these steps, you will have calculated the cumulative frequency for each product. The final cumulative frequency for the last product should match the sum of all frequencies, which in this case is 117.

#### How to Find Cumulative Frequency in Excel (More Than Method)

The "More Than" method is used to calculate cumulative frequency when you want to find the number of values that are greater than or equal to a certain class interval. Using the same table of products and frequencies as before, follow these steps to calculate the cumulative frequency using the "More Than" method:

1. Calculate the total frequency by summing all the frequencies. In this case, the total frequency is 117.
2. In the first cell of the cumulative frequency column, insert the formula "=SUM(\$B\$5:B5)". This formula adds up the frequencies from the first row to the current row.
3. For the second row and onwards, use the formula "=C5-B6". This formula subtracts the frequency value of the current row from the cumulative frequency of the previous row.
4. Copy the formula down the column to calculate the cumulative frequency for the remaining rows.

Following these steps will give you the cumulative frequency for each product using the "More Than" method. The final cumulative frequency for the first product should match the total frequency, which in this case is 117.

#### How to Create a Cumulative Frequency Graph in Excel

Once you have calculated the cumulative frequency in Excel, you can create a graph to visualize the data. To create a cumulative frequency graph, follow these steps:

1. Select the values or data in the cumulative frequency column.
2. Go to the "Insert" ribbon and find the "Recommended Charts" option under the "Charts" section.
3. Select the "Scatter" graph option and click "OK".

By following these steps, you will create an ogive curve or graph that represents the cumulative frequency data.

In conclusion, knowing how to find cumulative frequency in Excel is a valuable skill for data analysis. Whether you're using the "Less Than" method or the "More Than" method, Excel provides powerful tools to calculate and visualize cumulative frequency. By following the step-by-step instructions outlined in this article, you can easily perform these calculations and create informative graphs to better understand your data.
