If you know your data mean and its standard deviation, you can use the random number generator from the Excel Analysis ToolPak add-in or your own statistical data to chart a Gaussian curve.

With that, Excel can generate a series of random numbers based on the data entered and the standard deviation. With this data you can then create a curved chart, known as a bell curve.

Learn how to make a Bell Curve or generate a normal distribution cure in Microsoft Excel with data. This step by step illustrated guide will help you with that.
