Question 3

construct validity

Answer 3

does the study measure the full range of components that make up a behavior?

Question 4

criterion validity

Answer 4

does the measurement of a variable in one way relate to its measurement in another way?

Question 5

concurrent validity

Answer 5

does a new measurement or test measure the same thing as an old one that has already been validated - do the results concur?

Question 6

predictive validity

Answer 6

does the measurement of a behavior predict performance on another related measurement?

Question 7

Internal reliability

Answer 7

refers to how consistent the procedure or research is
are all participants experiencing the same thing?

Question 8

how do we assess for internal reliability

Answer 8

split half method
spilt the test in half
compare performance on one half of the test with performance on other half
a strong positive correlation indicates reliability

Question 9

external reliability

Answer 9

refers to if the procedure has been repeated and are the results consistent?
if test is repeated and gets the same results then its reliable

Question 10

how do we assess for external reliability

Answer 10

test re-test method
complete the test on more that one occasion
compare the performance on the tests
a strong positive correlation indicates reliability
