  a. Mixed methods approach
  b. Quantitative approach
  c. Qualitative approach
  d. Outcomes approach

Question 2

Subjects in a multiple group experimental study are tested for how much time it takes them to navigate a maze and find the chocolate. The maze is reconstructed after each run, and three different floor plans are used.
 
  Each group is tested eight times in eight hours. at a different time of day. The runs later in the day have faster times than the earlier ones. Which threat to internal validity might account for this difference?
  a. Instrumentation
  b. Selection
  c. Maturation
  d. Statistical regression toward the mean

Answer to Question 1

ANS: A
Mixed methods research is characterized as research that contains elements of both qualitative and quantitative approaches. The philosophical underpinnings of mixed methods research and what paradigms best fit these research methods are still evolving. Over the last few years, many researchers have departed from the idea that one paradigm or one research strategy is right and have taken the perspective that the search for the truth requires the use of all available strategies. A single approach to measuring a concept may be inadequate to justify a claim that it is a valid measure of a theoretical concept. Testing a single theory may leave the results open to the challenge of rival hypotheses from other theories. To capitalize on the representativeness and generalizability of quantitative research and the in-depth, contextual nature of qualitative research, mixed methods are combined in a single research study.

Answer to Question 2

ANS: C
Effects can be due to changes in measurement instruments (instrumentation) between the pretest and the posttest rather than a result of the treatment. Selection addresses the process by which subjects are chosen to take part in a study and how subjects are grouped within a study. Maturation is defined as growing older, wiser, stronger, hungrier, more tired, or more experienced during the study. The subkects in this study may have been through the three different floor plans enough times to learn them. Such unplanned changes can influence the findings of the study. Experimenter expectancy occurs when a researcher expects a particular intervention to relieve pain.
