Say I want to make a specific test. What is the correct terminology to describe the issue of having enough data to properly do it. Consider for instance:
"Of course the authors also needed to consider the issue of including enough data in order for their tests to be/have -INSERT WORD-".
One could of course say have the correct power/size, but this is specific issues so I guess I am looking for a kind of umbrella term meaning: without all the types of problems one encounters when the sample is too small.
