A coach wants to see if drinking water during a race improves times. To test this, he has his runners run around a track for 10
miles each practice, and lets half of them drink during the run, and half do not, varying the halves each day, for a 2 week period. This is an example of what kind of statistical study? 1.Experiment
2.Observational Study
3.Survey
This is an experiment. The coach has two groups, one control and one not, and independent)(run length) and dependent (water) variables. May I add that varying the groups is a smart move because it reduces the risk of injury to his players.
