When you want to analyze and graphs a set of experiments the same way, you can save your example as either a template or method. In either case, start from the data table, drop the File menu, choose Save Special..., and then choose Save Template or Save Method.
The difference is in when you choose to use these files.
•Open the template from the Welcome dialog, enter or import data, and then look at (and fine-tune) the results and graphs.
•Methods are different. First create a data table and enter or import data. Only then do you click the Analyze button to apply the method to your data.
Perhaps this distinction will help: A template is a noun - a place you start from. A method is a verb - something you apply to data you have already entered
