Ecological validity

External validity

Answer 7

The extent to which findings can be generalized to real-life settings.

Question 8

Temporal validity

External validity

Answer 8

The extent to which the research findings remain relevant overtime

Question 9

Predictive validity

The ability of results from a study to predict the future behaviour of participants that took part.

Question 10

Answer 10
