1 .		In the discussion section of the research report, the researchers mentioned their concern about the Hawthorne Effect. This means the researchers are concerned about which of the following? [Hint]   bias on the part of the researcher during selection of the sample   nonrandom assignment of subjects to research groups   the intentional or unintentional behavior of a researcher modifying the subjects' behavior in a research study   assess the adequacy of the research design
2 .		If a researcher wanted to assess the demand for a well baby clinic in the area, what type of design would be used? [Hint]   "one-shot case" design   experimental design   time-series design   survey
3 .		A researcher is interested in demonstrating that emergency room nurses have more work related stress than nurses do in intensive care units. Several stress indexes are given to the nurses in both groups. The scores from the indexes are then compared. What type of design would the researcher use? [Hint]   experimental   nonequivalent control group design   comparative design
4 .		The researcher is using an experimental design to explore a different teaching approach effect on cheating in the classroom. The control group is receiving the standard classroom environment. The experimental group is receiving the new approach, which includes in the classroom a teacher, two assistant teachers and two observers in lab coats. What threat to validity is strongest in the situation describe above? [Hint]   reactive effects of the pretest or measurement effect   selection bias   Hawthorne effect   maturation
5 .		The researcher is doing a study on attitudes regarding the national economy. He interviews the first 50 people leaving the auditorium. What is the threat to validity for this study? [Hint]   testing   selection bias   mortality   history
6 .		What type of design is the following: O1 X O2 O1     O2 [Hint]   Solomon four-group   pretest-posttest control group design   posttest-only control group design   Nonequivalent control group design
7 .		The researcher has decided to utilize a "time series" design. Which threat to validity should be the biggest concern to the researcher? [Hint]   history   selection bias   hawthorne Effect   experimenter effect
8 .		The researcher is interested in learning whether a self-administered psychological profile provides information comparable to an interview with a psychologist. The research approach to such a study would be: [Hint]   methodological study.   simulation studies.   exploratory studies.   post-test only control group design.
