Evidence-Based Practice / Unit 7   EBP 0932 short lesson, about 20 seconds

How Participants Were Chosen

Captions available

The idea

Appraisal asks how the study's participants were chosen, and whether the sample's composition and size reflect what the study needed.

In practice

Participants selected because they had lived the experience being studied.

Where people slip

Qualitative sampling is purposive by design. Judging it against representativeness applies a criterion from a different kind of study.
