How to Create a Box and Whisker Plot Calculator in Excel

Creating a box and whisker plot calculator in Excel can be a bit tricky, but with these steps, you'll be able to create one easily.

Step 1: Prepare Your Data

Before we start creating our box and whisker plot calculator, make sure your data is organized into three columns. Each column should have 30 entries from the following ranges: Step 2: Calculate Quartile Differences

To calculate quartile differences, create a second table and populate it with the following formulas:

* Minimum values

* Maximum values

* Median value

* First quartile (Q1)

* Third quartile (Q3)

These calculations will give you the correct values for your box plot.

Step 3: Create a Stacked Column Chart

Create a third table and copy the minimum values from the last table there directly. Then, calculate the quartile differences with the Excel subtraction formula (cell1 – cell2), and populate the third table with the differentials.

Next, create a stacked column chart by selecting all the data from the third table and clicking Insert > Insert Column Chart > Stacked Column. This will give you a basic box plot structure.

Step 4: Convert the Stacked Column Chart to the Box Plot Style

To convert your stacked column chart to a box plot style, first calculate the minimum, maximum, and median values, as well as the first and third quartiles, from your data set. Then, modify your stacked column chart by changing the formatting options.

In some box plots, the minimums and maximums outside the first and third quartiles are depicted with lines, which are often called whiskers. These whiskers can be added to your box plot by using Excel's formatting options.

Creating a box and whisker plot calculator in Excel may seem like a complex task, but by following these steps, you'll be able to create one easily. This box plot calculator is useful for statistical analysis, as it allows you to visualize the distribution of a set of data. With this tool, you can quickly identify trends and patterns in your data.
