PSYCH 2300 CH 13&14 EXAM WITH COMPLETE
SOLUTIONS
A professor wants to determine the efficacy of two different teaching methods: the
lecture method (LM) vs active learning method (ALM). The professor has two separate
sections of a psychology course. Students select which section they wish to enroll in.
Assume students don't know which teaching method will be used and will often choose
which section based on what works with their individual schedules. The design for the
study is summarized as follows:
Class section 1: LM chapter 5 -> quiz chapter 5
Class section 2: ALM chapter 5 -> quiz chapter 5
Assume that the quiz on chapter 5 is the exact same for both versions of course.
The above scenario describes a ___________.
Experiment
Quasi-experiment - answer quasi-experiment
A large prison decides to give prisoners access to yoga mats for use in their cells.
Researchers wished to determine if access to yoga mats improves prisoner's quality of
life as measured with a self-evaluation. Researchers wanted to assign prisoners to
groups who received yoga mats vs those who did not receive yoga mats but the prison
had rules governing equal access to amenities that prevented this research design.
Access was set by the prison so that yoga mat access was staggered so that different
areas of the prison were given access on a week by week basis. Researchers measured
all of prisoner's before, during, and after their assigned window of yoga matt access.
The above scenario describes a .
Experiment
Quasi-experiment - answer quasi-experiment
T or F: Laboratory settings will always lack experimental realism because ecological
validity can only be achieved in a field study. - answer false
T or F: Small N studies that use a stable baseline design are most vulnerable to
maturation and regression threats. - answer false
Which of the following statements is NOT consistent with improving internal validity.
-reversal designs in a small-n experiment
