Reliability & Validity

Question 1

reliability

Answer 1

degree to which measurements provide consistent data (because they are free from random error)

Question 2

test-retest reliability

Answer 2

when you repeat the measure, are the results the same?

Question 3

equivalent form reliability

Answer 3

two very similar forms of an instrument can produce close correlated results

Question 4

internal consistency reilability

Answer 4

ability of an instrument to produce similar results when used on different samples during the same time period

Question 5

split-half technique

Answer 5

assessing the reliability of a scale by dividing the total set of measurement items in half and correlating the results

Question 6

validity

Answer 6

degree to which research measures what should be measured

Question 7

face validity

Answer 7

the impression that that the measurement is valid

Question 8

content validity

Answer 8

extent to which a measure represents all facets of a given construct

Question 9

criterion-related validity

Answer 9

how well one measurement can predict the outcome of another measure

Question 10

predictive validity

Answer 10

future variable can be predicted by a current measurement

Question 11

concurrent validity

Answer 11

extent to which variables measured at the same point in time can be predicted by the measurement instrument

Question 12

construct validity

Answer 12

degree to which a measurement confirms a hypothesis.

Question 13

convergent validity

Answer 13

measures should theoretically be related and are

Question 14

discriminant validity

Answer 14

measures should not be theoretically related and are not
