b. Credible and valid
c. Reliable and valid
d. Reliable and trustworthy

a. When the dependent variable changes as the independent variable is manipulated.
b. When the independent variable changes as the dependent variable is manipulated.
c. There is no change when either of the variables are manipulated.
d. Both variables change when the independent variable is manipulated.
12. A researcher wants to know whether nursing fatigue is one cause of poor patient satisfaction scores. The independent variable is
a. Nursing fatigue
b. Patient satisfaction scores
c. Both nursing fatigue and patient satisfaction scores
d. Number of hours worked by the nurse during the week previous to measuring patient satisfaction scores.
13. A sampling technique used in experimental design includes
d. Voluntary selection
14. Causality is tested through which of the following?

b. Experimental research
c. All quantitative research
d. Descriptive research
15. Why does subject attrition affect internal validity?
a. A study in which the majority of the subjects die calls into question whether the treatment itself is safe
b. Subjects who drop out may differ from those who stay in the study, in terms of an important extraneous variable.
c. Type I error is almost guaranteed with very unequal sample sizes.
d. Subject mortality may result in a sample that is so much smaller than anticipated that type II error may result.

19. The plan for data analysis can be developed once the data collection is complete.
20. A mixed methods research design means two types of quantitative studies are used to collect and analyze the data.
21. In quantitative experimental research, the independent variable is manipulated to determine the effects on the dependent variable.
22. A research may choose to conduct a pilot study before the main study is conducted in order to determine if the data collection tool will measure the dependent variable accurately.
23. A random table of numbers may be used to select participants for an experimental study.
24. The pre-test post design is used in correlation research to show there is a relationship between the pre and post interventions.
25. The researcher must select an appropriate design for a study in order to eliminate error and make critique of the findings possible.
