Minitab Statistical Software displays the information that you need in the analyses that you perform, but it’s possible that you might want to capture information in a different place, or even a different program, so that the results are as easy to communicate as possible. For those occasions, it’s helpful to know how to get text even from the less obvious places in Minitab. Here are five useful cases:
In Minitab, you often can hover over part of a graph and get a yellow box with some text in it. Try this:
Now you have a boxplot that shows how different the thicknesses are for different settings. Leave your mouse pointer over one of the boxplots, and Minitab displays some of the sample statistics. To record those exact statistics for each boxplot, you need an additional step.
Right-click your boxplot and choose Send Graph to Microsoft Word. The boxplots and the copied statistics go right into your report.
The boxplot tooltips are great for getting the exact statistics the plots show. In scatterplot, you can use the same copying feature to display the equation of the regression line. Follow this example using the same data set that we used for the boxplot tooltips.
Now you have a nice scatterplot that shows a line. In real life, we’d dig deeper into this relationship before using the line because we can see that the variation increases with Setting. But we can still use this graph to illustrate how to get the equation for the line onto the graph.
Now, the equation is in your subtitle.
The line and the equation are nice, but for the most detail, use Minitab’s Assistant Menu. That’s also another place where you might not know how easy it is to copy!
Minitab’s Assistant Menu is a great tool that leads you through your analysis. One of the best parts of the Assistant Menu is that it provides a summary report to help you interpret your results with confidence. You can try it out for yourself on the same data set we used for the boxplots and scatterplot.
The Comments section includes the fitted equation, a reminder to inspect the fit before using the model to predict, and a caution that statistical significance does not mean that a change in X will cause a change in Y. If you want to emphasize just these comments, it’s as easy as getting the tooltip text.
You’re all set to discuss this portion of the Summary Report in detail.
Minitab’s Assistant Menu also includes guidelines to ensure that your analysis is successful. The first report in most Assistant Menu analyses is the Report Card, a great summary of checks on your data.
The Report Card for Regression includes four data checks. In a presentation, you might want to call attention to some of the checks more than others. In this case, you might want to spend extra time explaining just the Unusual Data check, because it has a caution symbol.
You’re ready to give more detail about the two data points with large residuals.
You can also edit the text in the Report Card. Double-click the text and you can add all the notes that you want.
You know that you can copy text from tooltips in Minitab graphs and from the Minitab Assistant Menu Reports. If your goal is to show someone else how to do an analysis in Minitab, an example can be a big help.
Suppose that you want to include the example of a scatterplot with separate lines for different groups in a Microsoft Word 2010 document.
Now you have the example, with formatted steps and graphical output, ready to share.
Minitab’s output includes a lot of detail. In a presentation or report, you might want to call attention to specific statistics or features. Knowing how to copy from all types of Minitab output and guidance can save a lot of time and effort. So grab those tooltips, Assistant Menu notes, and help examples, and use them to your heart’s content!
