reliability + validity

Question 1

reliability

Answer 1

consistency of results

Question 2

test-retest reliabilty

Answer 2

• do the test, then repeat - are the tests the same
• you use diff ppts for the repeat - no/reduce demand characteristics

Question 3

inter-rater reliability

Answer 3

2 observers, compare their results and do statistical analysis

Question 4

internal validity

Answer 4

• what’s going on inside the study
• is the DV actually being affected by the IV - demand characteristics will affect this

Question 5

external validity

Answer 5

• applying to outside the experiment
• wider repercussions of research

Question 6

construct validity

Answer 6

is it actually measuring the the underlying theoretical construct

Question 7

concurrent validity

Answer 7

does the test find similar results to a pre-existing test

Question 8

face validity

Answer 8

on the surface, does it look like what it’s going to measure

Question 9

temporal validity

Answer 9

is it valid today
(can it be applied today)

Question 10

population validity

Answer 10

• e.g. ethnicity, age, gender etc

Question 11
