The idea
The instruments a study uses are checked for whether they measure what they are meant to and do so consistently.
In practice
An instrument with established reliability and validity chosen over an ad hoc one.
Where people slip
Unit 04 defined validity and reliability for the appraiser. The designer's version is choosing instruments that already have them.
