Now that you know the essentials, let’s move from theory to practice. It’s worth mentioning the 68-95-99.7 rule that can be applied to any normal distribution curve, meaning roughly 68% of your data is going to be placed within one SD away from the mean, 95% within two SD, and 99.7% within three SD. The lower the SD, the taller the curve and the less your data will be spread out, and vice versa. For instance, in the bell curve shown above, one standard deviation of the mean represents the range between exam scores of 53 and 85. This defines the spread of your data in the normal distribution-or in plain English, how wide the curve should be. The standard deviation (SD) of the measurements.This determines the center of the curve-which, in turn, characterizes the position of the curve. The mean (also known as the standard measurement).To plot a Gaussian curve, you need to know two things:

In this step-by-step tutorial, you will learn how to create a normal distribution bell curve in Excel from the ground up: That’s why we developed the Chart Creator Add-in, a tool that allows you to build advanced Excel charts in just a few clicks. Since Excel doesn’t have any built-in solutions to offer, you will have to plot it yourself. The graph helps us analyze whether a particular value is part of the expected variation or is statistically significant and, therefore, has to be examined more closely. The y-axis represents the relative probability of a given value occurring in the dataset while the x-axis plots the values themselves on the chart to create a bell-shaped curve, hence the name. In statistics, a bell curve (also known as a standard normal distribution or Gaussian curve) is a symmetrical graph that illustrates the tendency of data to cluster around a center value, or mean, in a given dataset.

Download Normal Distribution Bell Curve Template.Step #12: Add vertical lines (optional).Step #11: Recolor the data markers (optional).Step #10: Insert and position the custom data labels.Step #9: Modify the horizontal axis scale.Step #8: Change the chart type of the label series.Step #7: Insert the label data into the chart.Step #5: Create a scatter plot with smooth lines.Step #4: Compute the normal distribution values for every x-axis value.Step #3: Set up the x-axis values for the curve.Return to Charts Home How to Create a Normal Distribution Bell Curve in Excel If you want to plot a quadratic with Excel you have to choose your #x# values carefully to try to include interesting points, such as, the vertex and the intercepts.Create, Save, & Use Excel Chart Templates My version of Excel is in Portuguese but in English doesn’t change a lot. In the formula bar (see the red arrow) you can see the form of the quadratic (accepted by Excel) and the corresponding calculated value. In the above Picture you can see the graph and the two columns for #x# and for the quadratic (in this case I've chosen: #x^2+2x-4#). I've chosen points and smoothed lines from the boxes on the right of the chart window: You can now choose to plot only the points or lines and points.

This is represented by the following icon (in the chart window): The right graph to use is the 'xy scatter'. Next I would select the two columns (highlighting them) and choose 'chart' from the menu 'insert'. I would start by choosing the first column of the spreadsheet for the values of #x# and the second for the correspondent calculated values of your quadratic.
