internal validity

Answer 4

when the outcome is the result of the variables that are manipulated in the study

Question 7

ecological validity

Answer 7

whether we can generalise the results from the settings of the study to other settings

temporal validity

Answer 8

whether the results are relevant today (no old research)

Question 9

face validity

Answer 9

a judgement about if a test seems to be valid

Question 10

concurrent validity

Answer 10

if the test shows similar findings to other existing measures

Question 11

Answer 11

measured by how well a test will predict future performance
