Scenario: Ben sees a commercial for a new energy drink (HeartRacer) that claims to keep you energized for longer than Red Bull. He decides to test this out. On Monday, he drinks a HeartRacer in the morning and measures his energy levels at 5pm. On Tuesday, he drinks a Red Bull in the morning and measures his energy at 5pm. He finds that he has more energy at 5pm when he drank the HeartRacer than when he drank the Red Bull. What is the independent variable for Scenario C?
a. Energy levels
b. Type of Energy Drink
c. Consumed Day of the week
d. The participants

Option B

Explanation:

In simple words, A dependent variable refers to the variable whose variance depends on some other component — generally a response variable. On the other hand, an  independent variable refers to the variable whose variance does not concentrate on any function though on the experimenter.

The autonomous variable is just as it looks like. It's a parameter that works out and isn't affected by any of the other parameters you're attempting to calculate. Thus, from the above we can conclude that the correct option is C.
