designs is that experimental design require - ANSWERS-Random
assignment to groups
You are the researcher studying work-place improvements to increase
worker morale. You do pretest measures of morale among workers at an
agency using the Work Morale Inventory (WMI), implement your
intervention of morale building activities and then do a post-test measure
of morale using the WMI, What design are you implementing? -
ANSWERS-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 you first WMI
measure, what internal validity might affect your study results? -
ANSWERS-Both a and b (history a, mortality b).
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? - ANSWERS-Instrumentation

Both a and b
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: -
ANSWERS-discriminant validity.
Cronbach's alpha is used to measure a scale's: - ANSWERS-internal
consistency reliability.
Discriminant validity is a type of: - ANSWERS-construct validity.
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
