Aims and objectives
Also searched as: Aim · Objectives · Primary objective · Secondary objective
The aim is the one sentence that says what the study is for. The objectives are the measurable steps that deliver it, and each should name a variable, a population and a comparison where there is one. Keep one primary objective that maps to one outcome and one statistical test; everything else is secondary. An objective that does not say what will be measured cannot be matched to a test, which is where a vague synopsis runs into trouble.
