You are a researcher studying work-place improvements to increase worker morale. You do a
pre-test measure of morale for 50 workers at an agency using the Worker Morale Inventory
(WMI), implement your intervention of morale building activities, and then do a post-test
measure of morale with them using the WMI. What design are you implementing?
AB design
the class experimental design
the one-group post-test only design
the one-group pre-test/post-test design
d. the one-group pre-test/post-test design
You are the researcher conducting the study described in question 7. If the agency had to lay off
several staff members after your first WMI measure, what threat to internal validity might affect
your study results?
a. history
b. mortality
1|Page
,c. both history and mortality
d. none of the above
both history and mortality
You are the researcher conducting the study described in question #7. If you used the WMI for
the pre-test, but decided to use the Workplace Burnout Scale (WBS) for the post-test, what
threat to internal validity might affect your study results?
a. instrumentation
b. testing
c. selection
d. history
a. instrumentation
You are the researcher conducting the study described in question 7. If you are including ALL of
the agency employees in your study, which threat to internal validity is LEAST LIKELY to affect
your study results.
a. selection
b. testing
c. history
d. maturation.
a. selection
Reliability and validity of a research instrument refer to:
a. the instrument's psychometrics
b. whether the instrument consistently measures what you want it to measure
c. both a and b
d. neither a nor b

, both the instrument's psychometrics and whether the instrument consistently measures what
you want it to measure
Cronbach's alpha is used to measure a scale's:
a. face reliability
b. internal consistency reliability
c. test-retest reliability
d. none of the above
b. internal consistency reliability
You and your co-researcher observe the same subject during the same time period and
independently record the number of times she "interacts inappropriately" with her child. When
you compare your results, you have very different numbers: your colleague says the subject
interacted inappropriately 32 times during the time period; you observed only 10 such
interactions. It appears that your measurement procedure has poor:
a. split-half reliability
b. interrater reliability
c. external reliability
d. test/retest reliability
b. interrater reliability
You are developing a scale to measure preparation for employment among vocational training
students. You decide to test the validity of your scale by administering it to 2 groups of workers:
group 1 is comprised of vocational training graduates who have been on the job for 1 year or
more; group 2 is comprised of first semester vocational training students. Your hypothesis is
that group 1 will score much higher on your scale than will group 2. you are testing your scale's:
a. concurrent validity
b. face validity
