Answer: how to draw Gaussian distribution graph
Yes, Microsoft Excel has a built-in function to draw a Gaussian distribution graph. Here are the steps to follow:
- First, you need to calculate the mean and standard deviation of your data set. You can use the and functions to do this.
- Next, create a new column next to your frequency data and label it "X". In the first cell under "X", enter the minimum value of your data set. In the cell below that, enter the next value in your data set, and so on, until you reach the maximum value.
- In the next column, label it "Y", enter the formula for the Gaussian distribution. The formula is:
Formula:
=NORMDIST(X,mean,stdev,FALSE)
. Replace "X" with the cell reference for the corresponding value in the "X" column, and replace "mean" and "stdev" with the cell references for the mean and standard deviation you calculated in step 1. - Copy the formula down the entire "Y" column to calculate the Gaussian distribution for each value in the "X" column.
- Highlight both the "X" and "Y" columns, and then click on the "Insert" tab in the ribbon.
- Click on the "Scatter" chart type, and then choose the "Smooth Line with Markers" option.
- Your Gaussian distribution graph should now be displayed on the worksheet.
That's it! You now have a Gaussian distribution graph that is relevant to your frequency data.
