4. 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

4. 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

Answer

Brief Explanations:

  • 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
