In a study examining the effects of caffeine consumption on reaction time, researchers found that participants who consumed caffeinated beverages showed faster reaction times compared to those who did not. Identify the independent variable, dependent variable, and explain the observed relationship. Question 5 options: Independent variable: Reaction time, Dependent variable: Caffeine consumption, Faster reaction time leads to increased caffeine consumption. Independent variable: Caffeine consumption, Dependent variable: Reaction time, Increased caffeine consumption leads to faster reaction times. Independent variable: Caffeine consumption, Dependent variable: Reaction time, Greater caffeine consumption leads to slower reaction times. Independent variable: Reaction time, Dependent variable: Caffeine consumption, Increased reaction time leads to greater caffeine consumption
