4.Which of the following measurement scales is accurately paired
with an example?

b. Coding religion as protestant = 1; catholic = 2, etc.
c. Temperature on a Celsius scale
d. Exam scores
8. ______________ refers to the consistency of results and
____________ is the extent to which you are measuring what you
think you are measuring.
a. Reliability; operational validity
b. Validity; reliability
* c. Reliability; validity
d. Convergence; divergence
9. Which of the following is TRUE?
a. A reliable measure is always valid

her test more than once. Which of the following methods of
establishing reliability would you suggest to Jenna?
a. Equivalent forms
* b. Internal consistency
c. Multidimensional
d. Concurrent
12. If we include items assessing memory, logic, and verbal
comprehension on an intelligence test – as opposed to food
preferences or shoe size – then we have satisfied which of the
following types of validity?
a. Discriminant

different operationalizations of the dependent variable.
c. is almost always found in published experiments.
d. is determined by replicating the results of your
experiment.
14. Which of the following illustrates reliability?
a. Dean takes an IQ test and scores at the 60th percentile.
b. Scores on a new test of reading comprehension correlate
highly with scores on well established reading
comprehension tests.
