Introduction

Creating a bell curve in Google Sheets requires using specific functions and formatting to visualize data distribution accurately. This guide will walk you through the necessary steps using actual formulas and chart options available in Google Sheets.

We'll start by gathering your data, then move on to using the necessary statistical functions, and finally, create the bell curve through precise chart formatting. Following these steps will help you effectively represent your data's normal distribution.

Instead of manually creating bell curves using complex Google Sheets functions, consider using Sourcetable, an AI-powered spreadsheet that lets you create visualizations through simple conversations. With Sourcetable, you can upload files of any size, generate sample data, analyze distributions, and create stunning charts just by telling its AI chatbot what you need.

How to Make a Bell Curve in Google Sheets

Step 1: Identify and Enter Data Points

Organize your data points into a single column or row in Google Sheets. Ensure there are no blank cells between the data points to facilitate accurate calculations.

Step 2: Calculate the Mean and Standard Deviation

Use the AVERAGE() function to calculate the mean and the STDEV() function to calculate the standard deviation of your dataset. Example: =AVERAGE(B2:B16) and =STDEV(B2:B16).

Step 3: Determine Standard Deviation Extremes

Calculate the Low and High standard deviation extremes using the formulas =D2-(E2*3) and =D2+(E2*3), respectively. This will help to define the range for your bell curve.

Step 4: Create a Sequence for the X-Axis

Generate a sequence of numbers for the X-axis using the formula =sequence(High-Low+1,1,Low). Insert a new column to the right of your data points and label it ‘Sequence’.

Copy the formula =sequence(H2-G2+1,1,G2) and paste it into the appropriate cell (e.g., C2).

Step 5: Calculate the Normal Distribution

Use the formula =ArrayFormula(NORM.DIST(Data Cell Range ,Average,Standard Deviation,false)) to calculate the normal distribution. Example: Copy the formula =ArrayFormula(NORM.DIST(C2:C57,$E$2,$F$2,false)) and paste it in cell D2.

Step 6: Chart the Data

Select the columns containing the sequence and normal distribution data. Insert a chart and choose the Scatter Chart type to visualize the bell curve.

By following these steps, you can effectively create a bell curve in Google Sheets to represent a normal distribution for data analysis.
