Concept explainers
Explain whether each situation represents an experiment or an observational study and if it is an experiment find the control group and the treatment group.
Answer to Problem 75SR
It is an experiment.
Explanation of Solution
Given:
It is given in the question that there are
Since, the two groups are told what to do. So, this is not an observation because the control group is the group where nothing is changed, to have something to compare to.
Hence, it is an experiment. The control group doesn’t exercise and the treatment group does.
