Validity

Question 1

What is validity?

Answer 1

This refers to how accurate a test/study is.

-(There’s 3 types- internal, external and ecological).

Question 2

What’s internal validity?

Answer 2

This refers to whether the test/method used is actually testing what it’s intended to. Whether the IV is causing the DV, this is low when a study is poorly controlled/has extraneous variables.
[if high then the IV is affecting the DV]
[if low, other factors (extraneous variables) might be affecting the DV].

Question 3

What’s external validity?

Answer 3

This refers to whether the results from a study can be generalised to other settings/people beyond the original sample/setting studied.
[if high then yes they generalise]
[if low then no they don’t generalise].

Question 4

What’s ecological validity?

Answer 4

This is a form of external validity, it’s the extent to which the results of a study can be generalise from the set of environmental conditions created nu the researcher to real life circumstances.
