Reading a Cross-Sectional Design
Captions available
The idea
A cross-sectional design supports statements about age differences and not about change within a person.
In practice
A technology-use study across three age groups reports a difference that may be entirely a cohort effect.
Where people slip
Every cross-sectional age difference is a candidate cohort effect until a second design rules it out.
