Reliability & Validity

Question 1

reliability

Answer 1

consistency of results

Question 2

ways of assessing reliability

Answer 2

-the test retest method
-inter observer/ inter rater reliability

Question 3

the test retest method

Answer 3

measures external reliability by giving the same test to the same ppts on two occasions to see if the same results are obtained. if results are the same, reliability is established

Question 4

inter-observer reliability

Answer 4

assesses whether different observers (min of 2) are viewing and rating behaviour on the same way. results with a strong positive correlation of more than 0.8 have high inter observer reliability

Question 5

validity

Answer 5

the degree to which something measures what it claims to, and also how generalisable the findings are beyond research settings

Question 6

face validity

Answer 6

a simple way of assessing validity and involves the extent to which items on a test look like they’re measuring what they’re claiming to measure

Question 7

concurrent validity

Answer 7

assesses validity by correlating scores on a test with another test of the same behaviour, which has been tested for validity. a strong positive correlation indicates validity

Question 8

temporal validity

Answer 8

assesses to what degree research findings remain true over time. a form of external validity

Question 9

ecological validity

Answer 9

the extent to which results can be generalised to other settings and situations. a form of external validity
