Briefly |
Choose Test Hypothesis from the Analyze menu, then choose what type you want in its popup menu. |
You create an empty hypothesis test either by dragging one off the tool shelf or by choosing Test Hypothesis from the Analyze menu. Choose the kind of test from the popup menu. Drag attributes into the slots at the top of the test.
If you drag no attributes, you can still use most of the tests by editing the summary statistics in the test. (They're calculated for you if you use attributes from a collection.)
Attribute types |
Test types |
One continuous attribute |
|
Two continuous attributes |
|
One categorical attribute |
|
Two categorical attributes |
|
One continuous and one categorical |
Compare Means (two-sample t) (if the categorical attribute has exactly two values) |
Note: to do a paired t-test, create a new attribute containing the difference between the two elements, and do a Test Mean to see if that difference is equal to zero.
