Designing a Controlled Experiment to Test Sports Drink Claims
Hypothesis of the Experiment
Control Group
Control Group: A group of runners who do not consume the sports drink but instead drink a placebo beverage that resembles the sports drink in taste and appearance but lacks the active ingredients.Experimental Group
Experimental Group: A group of runners who consume the actual sports drink.Constants or Controlled Variables
Constants: All runners are subjected to the same environmental conditions, follow similar training regimes, have comparable rest before the experiment, and are of similar age and athletic ability.Type of Data Collected
Data Collected: Recorded run times of all participants to measure differences in running speed between the groups.Specific Observation
Observation Expected: The experimental group, on average, will run faster than the control group, indicating the sports drink may have a positive effect on running speed.A controlled experiment to test a sports drink manufacturer's claim includes a hypothesis, a control group consuming a placebo, an experimental group consuming the sports drink, controlled variables such as environment and training, data on run times, and the expected faster running times for the experimental group if the claim is true.
To test the claim of the sports drink manufacturer that their beverage leads to faster running speeds, we can design a controlled experiment with the elements mentioned above. This experiment aims to determine if there is a significant difference in performance between those who consume the sports drink and those who do not, thus testing the manufacturer's claims.
