In the Y Values box, delete the range reference, and then select the range F3:F10.Ĭlick the Name box, and then select cell E14.Ĭlick the X Values box, and then select the range E3:E10. In the X Values box, delete the range reference, and then select the range E3:E10. In the Name box, delete the cell reference, and then select cell E15. Note: Just below these 5 sub-types, the description will say 'Scatter with data points connected by smoothed lines without markers.' Under Chart sub-type, in the middle row, click the chart on the right. Select the range of cells, E2:H10, on the worksheet. To create a histogram for the original data, follow these steps:Ĭreate labels for the legend in the chart by entering the following: In the Analysis Tools box, select Histogram, and then click OK. To create a histogram for the random data, follow these steps: This will generate 2,000 random numbers that fit in a normal distribution. In the Output Options pane, click Output Range. In the Standard Deviation box enter the number calculated in cell B4 (14.68722). In the Parameters pane, enter the number calculated in cell B2 (29 in the example) in the Mean box. Note: Varying this number will increase or decrease the accuracy of the bell curve.

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.
