Miller et al. (2007) found that exotic dancers received an average of 15 more in tips per hour on the days on which they were at their highest fertility levels compared with days when they were at their lowest levels. Compared with laboratory experiments on evolutionary psychology, what advantages does this study have?
A) It maintained some level of precision while greatly increasing both forms of generalizability.
B) The use of tipping as a dependent variable increased levels of internal validity.
C) It allowed researchers to control the independent variable in ways that were impossible in the lab.
D) It disproved previous findings on the topic that were conducted in the laboratory.
Question 2
Miller et al. (2007) studied the amount of tips that exotic dancers received based on where the dancers were in their fertility cycles. They made separate comparisons for dancers whose hormones were artificially regulated with birth control pills. What type of procedure did this require?
A) matching
B) median split
C) patching
D) random assignment
