# How to Create a Bell Curve in Google Sheets (Step-by-Step)

A “bell curve” is the nickname given to the shape of a normal distribution, which has a distinct “bell” shape: The following step-by-step example shows how to make a bell curve in Google Sheets for a given mean and standard deviation.

### Step 1: Define the Mean & Standard Deviation

First, we’ll define the values for the mean and standard deviation of a given normal distribution: ### Step 2: Define Percentiles

Next, we’ll define the percentiles to use in the plot ranging from -4 to 4 in increments of 0.1: ### Step 3: Define Data Values

Next, we’ll create a column of data values to use in the plot using the following formula: ### Step 4: Find the values for the Normal Distribution PDF

Next, we’ll use the following formula to find the values for the normal distribution probability density function: ### Step 5: Create the Bell Curve

Lastly, we can highlight the values in the range B5:C85, then click Insert and then click Chart.

The following bell curve will automatically be created: You’ll notice that if you change the mean and standard deviation, the bell curve will update automatically.

For example, here’s what the bell curve turns into if we use mean = 10 and standard deviation = 2: Feel free to modify the chart title, add axis labels, and change the color if you’d like to make the chart more aesthetically pleasing.
