Row 6 ( Upper quartile, Q3) is calculated by: The value after the comma (in blue above) show that we want the lower quartile (Q1) Row 3 ( Lower quartile, Q1) is calculated by: Excel has a built in function “quartile” which we can use for the calculation for this row and for row 6. The minimum and maximum values will be used to create the whiskers of the box plot. I will come back to row 3 in a moment, for now let’s skip on to rows 4 and 5.Īgain, repeat this for each site (and tab) to form rows 4 and 5 of the table above. The $ symbol ensures that the range used for column C never changes when you copy / paste the calculation across the row. Repeat this for each site (and tab) by changing the figure ‘1’ to ‘2’, then ‘3’ etc to form row 2 of the table below. ‘1’ refers to tab “1” and it is looking at the values in column C from lines 2 to 13. You can see this on the “Box plot” tab of the excel sheet attached. The first thing you need to do is calculate the median, minimum, maximum and upper quartile values for each site. You can of course use just one tab for all if you prefer! In the example attached, I have created a tab in excel for each site (labelled 1 to 10).

For clarification, I have also uploaded the excel file, so please feel free to have a look! In this example, I have 10 sites, with values by month for the year 2011. So I thought I would post this technique to allow you to perform a box plot analysis using Excel.įirst you need to gather your data together. The Min and Max will be used by the high-low lines, and the intermediate Mean and Median have no effect on the added features.For those who rely on Excel to do their data analysis (rather than mini-tab or JMP), occasionally the charts available are a little limiting. The First and Third Quartiles are listed first and last so the up-down bars represent the inner quartiles of the box plot. We’ll start with this set of calculations, based on three samples of a larger population that has mean of 25 and standard deviation of 10. If you start with a line chart and add these graphic features, the arrangement of data is ignored. Excel 2007 insists on price data in columns only. Excel 2003 allows the price data to be arranged in columns (as such data is usually provided) or in rows. Excel 2003 also accepts data in Open-Low-High-Close order, while Excel 2007 insists upon OHLC. When data is entered in Open-High-Low-Close order, the up-down bars and high-low lines are used to create candlestick-style stock charts in Excel.

The formatting of up bars (the last series is greater than the first) is distinct from that of down bars (the last series is less than the first).Ī stock chart is simply a line chart that uses these embellishments. I’ve described these embellishments in Microsoft Excel Stock Charts (scroll down to “Home-Made OHLC Candlestick Chart”) When two or more line chart series are present in a chart, the up-down bars draw vertical bars from the first line series to the last, and the high-low lines are drawn behind the up-down bars (if present) from the lowest to highest line series value. This simple approach uses line charts, and the up-down bars and high-low lines that can be added to line charts. There is a simpler technique that works for vertical box plots with positive and negative values, without loads of column series. These techniques are complicated, since they are built using bar or column charts, with extra sets of series to accommodate data sets with positive and negative numbers.

I’ve also created a professional Box Plot Utility that generates box and whisker charts from raw observations. I’ve written several tutorials about creating box and whisker charts, including Horizontal Box Plots and Vertical Box Plots.
