How To Do A Bell Curve In Excel

Create a bell curve in Excel by using the appropriate statistical functions such as NORM.DIST and plotting the data points on a graph.

Excel is a powerful tool that can assist in organizing, analyzing, and presenting data in various ways. One common method of visualizing data is by using a bell curve, also known as a normal distribution curve. The bell curve is widely used in statistics and data analysis to understand the distribution of a data set and identify patterns and trends. In this blog post, we will explore how to create a bell curve in Excel, guiding you through the step-by-step process to effectively visualize your data and gain valuable insights. Whether you are a student, researcher, or business professional, learning how to do a bell curve in Excel can enhance your data analysis capabilities and bring your findings to life. So, let’s dive in and discover the power of Excel in creating a bell curve!

How To Do A Bell Curve In Excel: Step-by-Step


Step 1: Open Microsoft Excel

Click on the familiar Excel icon to effortlessly launch Microsoft Excel, a powerful application designed for creating professional-grade bell curves with ease and precision. Get ready to showcase your data in a visually appealing and informative way!

Step 2: Input Your Data

To create a bell curve, you need to input your dataset of numbers into either a single column or row in a spreadsheet. This dataset will represent the values for which you want to analyze the distribution.

Step 3: Insert Blank Chart

To create a scatter plot with smooth lines in Excel, go to the “Insert” tab, choose “Charts,” select “Scatter,” and then click “Scatter with Smooth Lines” option.

Step 4: Set your data

This process is used to add a bell curve to a graph in Microsoft Excel. Once the graph is selected, clicking on “Select Data” will open a window. Within this window, the ‘Add’ button under “Legend Entries (Series)” is clicked. In the ‘Series X values’ field, you input the range of your data (for example, A2:A10). However, for the ‘Series Y values’, you delete any existing values and simply input ‘1’. The reason for this is that the Y values of a bell curve are not based on your data, but rather on the predefined values that create the shape of a bell curve.

Step 5: Generate a Normal Distribution Curve

To generate a normal distribution curve, calculate the mean and standard deviation of the data in cells C1 and C2 respectively. Then use the NORM.DIST function in cell B2, with the data in A2 as the first argument, the mean in C1 as the second argument, the standard deviation in C2 as the third argument, and FALSE as the fourth argument. Drag the formula down to complete the curve.

Step 6: Add the Curve into the Chart

After clicking on the graph and selecting “Select Data”, click the ‘Add’ button under “Legend Entries (Series)”. Input your data range (A2:A10) for ‘Series X values’ and the range of your newly generated normal distribution data (B2:B10) for ‘Series Y values’.

Next Step

Step 7: Format your Graph

After accessing the graph, go to “Chart Tools” in the toolbar. Under “Design”, select “Select Data”. Within the Legend Entries section, locate ‘Series1’ and eliminate it using the ‘Remove’ button. Now, solely the bell curve will appear on your graph.
