Correlational, measuring variables over time. Multiple assessments over time.

ex: sun exposure + mood, over the span of different seasons

Question 6

How does research design impact internal and external validity?

Answer 6

More control in research design -> greater internal validity and less external validity

Question 7

External validity

Answer 7

is it generalizable to the general population?

Question 8

Internal validity

Answer 8

Is it researching what it aims to measure?

Question 9

Answer 9
