**Excel **is a powerful software. We can perform numerous operations on our datasets using **Excel **tools and features. With the help of various charts and graphs, you can effectively present survey results. Sometimes, we perform mathematical operations in **Excel**. They can include **Statistics **at times. The **Normal Distribution** comes along whenever dealing with **Statistics**. This article will show you the step-by-step procedures to **Plot Normal Distribution **in **Excel**.

## Introduction to Normal Distribution

The **Normal Distribution **is also known as the **Gaussian Distribution**. It is a **probability distribution** of data that is symmetric to the mean. We need the **Mean **and **Standard Deviation **of the data first to calculate the **Normal Distribution**. The **Mean **is the **average **value of all data. And the **Standard Deviation **measures the deviation of a particular data from the mean value.

## Step by Step Procedures to Plot Normal Distribution in Excel

We’ll use **the ****NORM.DIST**** function** to find the **Normal Distribution **in** Excel**. This function needs **4 **arguments.

** x**: The data for which we’ll determine the normal distribution.

** mean**: The average value of the dataset.

** standard_dev**: Measured standard deviation of the dataset.

** cumulative**:

**TRUE**represents the cumulative distribution function.

**FALSE**represents the probability mass function.

To illustrate, we’ll consider the below dataset as an example. For instance, the dataset contains **Student Names **and the obtained **Marks**. Now, go through the steps below carefully to determine the **Normal Distribution **of the **Marks **in **Excel**. Then, we’ll plot it.

### STEP 1: Find Mean & Standard Deviation

Let’s calculate the **Mean **& **Standard Deviation **in our first step. We’ll apply **the AVERAGE function** to find the mean. Then we’ll insert **the STDEV function** to get the standard deviation.

- First, merge the cell range
**D5:D12**. - Then, in cell
**C5**, type the formula:

`=AVERAGE(C5:C12)`

- Subsequently, press
**Enter**. - Thus, it’ll return the
**Mean**.

- Similarly, merge the range
**E5:E12**. - After that, type the below formula in cell
**E5**:

`=STDEV(C5:C12)`

- Press
**Enter**. - Hence, you’ll get the
**Standard Deviation**.

### STEP 2: Create Normal Distribution Chart

We have to find the normal distribution points for each mark.

- Firstly, click cell
**F5**. - Now, insert the formula:

`=NORM.DIST(C5,$D$5,$E$5,FALSE)`

- Next, press
**Enter**. - You’ll get the normal distribution point for cell
**C5**.

- Afterward, use
**the AutoFill tool**to complete the series. - As a result, it’ll return all the values.

### STEP 3: Plot Normal Distribution in Excel

In this step, we’ll demonstrate how to plot normal distribution in **Excel**.

- In the beginning, select the
**Marks**range**C5:C12**. - Next, choose
**Home ➤ Editing ➤ Sort & Filter ➤ Sort Smallest to Largest**.

- Consequently, a warning dialog box will pop out.
- Check the circle for the second option.
- Then, press
**Sort**. - See the following picture to understand better.

- Thus, it’ll return the sorted marks column.

- Again, select
**Insert ➤ Insert Scatter or Bubble Chart ➤ Scatter with Smooth Lines**.

- As a result, you’ll get the normal distribution graph.
- The below figure demonstrates the outcome.

### STEP 4: Modify Chart

To make the **Normal Distribution **chart more presentable, we’ll perform some changes.

- Double-click on the
**Chart Title**. Rename it as**Normal Distribution Graph**. - Click on the chart. Press the
**+**symbol present beside the chart as shown below. - Check the boxes for
**Axes**,**Axis Title**and**Chart Title**. - To remove the gridlines, uncheck the
**Gridlines box.**

- Now, double-click the
**Y-axis**. - As a result, the
**Format Axis**pane will appear. - Set the
**Minimum Bounds**as**60**.

- Similarly, double-click the normal distribution curve line.
- Consequently, you’ll get the
**Format Data Series pane.** - Check the circle for
**Built-in Marker Options**.

### Final Output

After performing all the modifications, our **Normal Distribution** graph is finally ready to demonstrate. The below figure is the final output.

## Things to Remember

- To avoid errors, sort the data before plotting the normal distribution.
- The mean and standard deviation should be in numbers.
- To avoid
**#NUM!****Error**, make sure the standard deviation is greater than zero.
