How to Generate Box-Whisker Plots Using Statlets


1. When you start Statlets, the following spreadsheet should appear. If not, click on the "File" pull down window and select "New."


2. Click on "Col_1" and the entire row should become shaded.

3. Type a new variable name, let's use "Weight" then press return: Then enter the following numbers, pressing return after each one:











4. Click on the "Analyze" menu, slide down to "One Sample" and slip over to "One Variable Analysis."

the following dialog box will appear:

5. Click on "Weight" then click on arrowhead that is pointing away from Weight.

6. Click on the "Boxplot" tab and the following should appear.

The little red cross symbolizes the mean. This is appropriate for interval or ratio data but not for ordinal data. Also, in this case the whiskers cover all the data, but this program does not do this if there are "outliers."

7. To remove the red cross and insure that the whiskers cover all the data, select the [Options] button.

Make sure that "Median notches," "Mean symbols," and "Flagged outside points" are all clear of check marks.

Then press the [OK] button.

8. Now we want to save this graph by either printing it or doing a screen capture.

To print, click on the "File" pull-down menu and select "Print." The following dialog box will appear.

Make sure that the radio button for "Current tab only" is selected as shown above, then press the "OK" button.

Instead of printing, or in addition to it, you can do a screen capture and then paste the screen image into a document. To do a screen capture, hold down the "Alt" key as you press the "Print Screen" key. This puts the active window (your results) in your computer's clipboard. Now, without closing Statlet, open your word processor (Word, Works, WordPerfect, etc) and do a paste (either Edit/Paste or hold down the "Ctrl" key as you press the "v" key). All the images in this tutorial were done using this method of screen capturing. Note: if you press the "Print Screen" key without pressing the "Alt" button, you will capture the entire screen and not just the active window (which is all we need to capture) for our purposes.

Just for fun: Click on the other tabs and see what you see.
