When to use a nested t test in GraphPad?
If you swapped the data for Room 2 and Room 3, the result would be the same. There is no connection between, say, the second subcolumn for the control data and the second column for the treated data. •In this example, note that the subcolumns do not have the same number of values. The nested t tests works fine with unequal sample sizes.
Is it possible to reuse nested tests in IDE?
3.1 For big class, we should consider the @Nested tests, all tests in a single test class (in a hierarchical structure), and the hierarchical output in IDE makes the tests more readable. Furthermore, we can also initialize an object and reuse for all the nested tests.
How to use the nested annotation in JUnit 5?
