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.

The study by Miller et al. (2007) has advantages over laboratory experiments on evolutionary psychology as it maintained precision but greatly increased both forms of generalizability. The study took place in a naturalistic setting where the dancers interacted with real customers and received real tips, unlike in the laboratory experiments where participants are usually given artificial tasks or stimuli. This naturalistic setting increased the study's ecological validity or external validity. At the same time, the study also used strict controls on the participants' stages in their menstrual cycle, which increased its internal validity. Therefore, the study maintained precision while greatly increasing both forms of generalizability, making it an advantage over laboratory experiments.
