In the Number of Random Numbers box, type 2000. In the Analysis Tools box, click Random Number Generation, and then click OK. To generate the random data that will form the basis for the bell curve, follow these steps: Select Cell C3, grab the fill handle, and then fill the formula down from cell C3 to cell C8. This formula adds one standard deviation to the number calculated in the cell above.

This number represents three standard deviations less than the average. This generates the lower limit of the bin range. These formulas will generate the average (mean) and standard deviation of the original data, respectively.Įnter the following formulas to generate the bin range for the histogram: To create a sample bell curve, follow these steps:Įnter the following column headings in a new worksheet:Ī1:Original B1:Average C1:Bin D1:Random E1:Histogram G1:HistogramĮnter the following data in the same worksheet:Įnter the following formulas in the same worksheet: From the histogram, you can create a chart to represent a bell curve. After Microsoft Excel generates a set of random numbers, you can create a histogram using those random numbers and the Histogram tool from the Analysis ToolPak. N the following example you can create a bell curve of data generated by Excel using the Random Number Generation tool in the Analysis ToolPak. This article describes how you can create a chart of a bell curve in Microsoft Excel. A bell curve is a plot of normal distribution of a given data set.
