Choosing the test a design supports
The questions ask you to work out which standard error a described study supports and to judge what somebody else concluded from a p-value. The formulas come back readily; spotting a paired design described in unfamiliar words does not.

What this covers
- Choose the test a design supports
Given a described study, the learner can identify the unit of analysis and the data structure, paired or independent, one sample or two, and select a test whose standard error matches that design.
- Assemble a test statistic and state what it establishes
Given an estimate, a null value and the design's standard error, the learner can compute the standardized distance, name the reference distribution with its degrees of freedom, and state what the result does and does not establish, treating failure to reject as inconclusive rather than as evidence for the null.
