Microsoft Excel Tutorial: Place people on a bell curve.

Welcome to the MrExcel netcast, where we bring you the best tips and tricks for mastering Excel. In this episode, we will be discussing how to place people on a bell curve using Excel. This question comes from Jimmy, who attended one of my seminars in Huntsville, Alabama. He wants to summarize his data and plot it on a bell curve, and I'm here to show you how it's done.

If you're familiar with my YouTube channel, you may have seen my video on creating a bell curve in Excel. In that video, I used a series of fake X values to create a nice looking curve. However, in this episode, we will be using the actual data of people and their scores to create the curve. So let's get started.

First, we will create a pivot table with the people's names on the left and their average scores. Then, we will sort the pivot table from highest to lowest and remove the grand total at the bottom. Next, we will calculate the mean and standard deviation of the scores, which will be used to determine the height of each person on the bell curve.

Now, here's where the magic happens. We will use the NORM.DIST function to calculate the y-value for each person, using their x-value, the mean, and the standard deviation. Then, we will copy this data to a new range and create an XY scatter chart with smooth lines. If you're using Excel 2010 or earlier, you will need to use the Chart Labeler add-in by Rob Bovey to label the points. But if you're using Excel 2013 or newer, you can easily label the points by selecting Data Labels and choosing "From Cells" to specify the names.

To make the chart look more presentable, we can adjust the scale along the bottom and move any labels that may be overlapping. And just like that, we have successfully placed people on a bell curve using Excel. This is a great way to visualize and analyze data, and I'm sure Jimmy will find it very useful.

I want to thank Jimmy for this awesome question and for inspiring this episode. And thank you for tuning in to the MrExcel netcast. I'll see you next time for more Excel mastery.

Jimmy from Huntsville wants to arrange people on a bell curve
Use a pivot table to figure out the average score.
Sort the pivot table so the scores are arranged low to high. These scores will be the X values.
In an extra cell, calculate the AVERAGE() and STDEV() of the scores.
Use formulas to copy the data from the pivot table to a new range
Calculate a Y value for each person with =NORM.DIST(A2,Mean,StDev,False)
Create an XY Scatter chart with smooth lines
In Excel 2010 or Earlier, use Rob Bovey's Chart Labeler add-in (Google it…)
In Excel 2013, Add Data Labels, From Cells, Specify the names
Micro-adjust the chart to change the scale and move the labels that overset each other
