The statistical question that would best be answered by an experiment is: "Does taking a pre-workout supplement increase the number of calories burned during a workout?"
This question is experimental in nature because it involves manipulating a variable (the intake of a pre-workout supplement) to observe its effect on another variable (the number of calories burned), which is characteristic of experimental design.
