Feedback
Correct A nonequivalent control group design is a quasi-experimental design.
After-only nonequivalent control-group design is a quasi-experimental design.
A one-group pretest-posttest design is a quasi-experimental design.
A times-series design is a quasi-experimental design.
Incorrect A Solomon four-group design is an experimental design.
An after-only design is an experimental design.

Answer to Question 2

ANS: D, E

Feedback
Correct The type of support surface is one of the specified interventions or treatments (independent variables).
Nutritional supplementation is one of the specified interventions or treatments (independent variables).
Incorrect Rate of wound healing is the dependent variable.
Sacral myocutaneous flap failure is the type of wound being studied.
The retailer of the protein supplement is not an independent variable in this study. It would be an independent variable if two different retailers' supplements were being compared.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
