Any Data Desk analysis can become a template for similar analyses of other data. Data Desk's template tools make it easy to build a fully self-documented drag-and-drop interface for combinations of analyses and plots. Just do the analysis once to show Data Desk what you want. Data Desk's visual Action Control Language lets you add loops, conditional decisions, and other basic controls with no need ever to write a program or macro. Template files can be shared with others -- even with those using Data Desk on another operating system.

Here, we show a template to compute an F test for the ratio of two variances.
