Question

1. problem: if you drink more caffeine will your reaction times increase? experiment: measure the reaction time of an individual with different amounts of caffeine: no caffeine, a cup of tea, a cup of coffee, and 2 cups of coffee. part of experiment answer independent variable dependent variable constants experimental groups control group

Explanation:

• Independent Variable: The factor that is changed or manipulated. Here, it's the amount of caffeine consumed.
• Dependent Variable: The factor that is measured and is expected to change due to the independent variable. So, it's the reaction time.
• Constants: Factors that are kept the same throughout the experiment like the individual being tested, the method of measuring reaction - time.
• Experimental Groups: Groups that receive the treatment (different amounts of caffeine). Here, it's the groups having a cup of tea, a cup of coffee, and 2 cups of coffee.
• Control Group: The group that does not receive the treatment. In this case, it's the group with no caffeine.

Answer:

• Independent Variable: Amount of caffeine consumed
• Dependent Variable: Reaction time
• Constants: The individual being tested, method of measuring reaction - time
• Experimental Groups: Group with a cup of tea, group with a cup of coffee, group with 2 cups of coffee
• Control Group: Group with no caffeine
