Question 18

Extent to which a concept is accurately measured in a quantitative study.

Answer 18

Validity

Question 19

Important consideration in the choice of a research instrument.

Answer 19

validity

Question 20

Extent to which results permit researchers to draw warranted conclusions about the characteristics of the individuals studied.

Answer 20

validity

Question 21

Types of Validity:

Answer 21

content, construct, criterion

Question 22

It looks at whether the instrument adequately covers all the content that it should with respect to the variable.

Answer 22

content validity

Question 23

Refers to whether you can draw inferences about test scores related to the concept being studied.

Answer 23

construct validity

Question 24

Meaning that the instrument measures one construct.

Answer 24

Homogeneity

Question 25

Occurs when the instrument measures concepts similar to that of other instruments

Answer 25

Convergence

Question 26

Evident when behavior is similar to theoretical propositions of the construct measures in the instrument.

Answer 26

theory evidence

Question 27

- Any other instrument that measures the same variable. - Correlations can be conducted to determine the extent to which the different instruments measure the same variable.

Answer 27

criterion validity

Question 28

Shows that an instrument is highly correlated with instruments measuring similar variables.

Answer 28

Convergent validity

Question 29

Shows that an instrument is poorly correlated to instruments that measure different variables.

Answer 29

divergent validity

Question 30

Instrument should have high correlations with future criterions.

Answer 30

predictive validity

Question 31

Relates to the consistency of a measure.

Answer 31

reliability
