![]() The Q1, Median, Q3 and Mean values for Brand A in the range F12:F17 are calculated by the formulas =QUARTILE(A4:A13,1), =MEDIAN(A4,A13), =QUARTILE(A4:A13,3) and =AVERAGE(A4:A13). ![]() To create this box plot manually, you need to first create the values in range F12:F17. We now show how to construct this output manually using standard Excel capabilities. ExamplesĮxample 1: Repeat Example 2 of Special Charting Capabilities, showing outliers. The other difference is that we need to manually add a small circle or each data value greater than Q3 + 1.5*IQR or less than Q1 – 1.5*IQR. Similarly, the bottom whisker ends at the smallest data value greater than or equal to Q1 – 1.5*IQR. One key difference is that instead of ending the top whisker at the maximum data value, it ends at the largest data value less than or equal to Q3 + 1.5*IQR. ![]() The procedure for manually creating a box plot with outliers (see Box Plots with Outliers) is similar to that described in Special Charting Capabilities.
