Problem 1:
A 2012 study investigated the impact of psychological stress on men's judgments of female body size. The men were randomly assigned to one of two groups; one group was assigned to participate in a stressful task while the other group did not take part in the task. Then the men were asked to rate the attractiveness of female bodies varying in size from emaciated to obese.
a. What are the cases in this study?
b. Briefly explain why this is an experiment and not an observational study.
c. Identify the explanatory variable in this experiment.
d. Identify the response variable in this experiment.
e. Is a control group used in this experiment? If so, which group is the control group?
Homework Answers
(a) The case study here is to asses the impact of psychological stress on men's judgments of female body size.
(b) This is an experiment because the men were assigned, at random, to one of two treatments (stressful task or not). Because their normal behavior was modified, this is not an observational study.
(c) Type of task (stressful or not)
(d) Rating of the attractiveness of the female body sizes
(e) Yes, a control group is used. The group that did not participate in the stressful task is the control group.

Identify the use of appropriate experiment e Page(s) 9-10 In a study published in the journal Environmental Science and Technology in 2001, scientists were testing the endocrine disruptor hypothesis, which states that certain chemicals can interfere with hormone regulation in many organisms, leading to disorders such as the feminization of males. The scientists used juvenile fish and exposed them to either tap water or varying concentrations of treated sewage effluent (containing an array of chemicals). For this experiment,...
