A study was conducted at the local skate park to determine how caffeine affected the performance of skateboarders during competitions. 100 skateboarders were selected from an upcoming competition roster. The researchers chose a random entry then proceeded to select every 4th entry until the desired sample size was reached. On the day of the competition, the sample was split (at random) into two groups. Each member of Group "A" was given a cup of decaf coffee while each member of Group "B" was given a cup of coffee containing 100mg of caffeine. (The skateboarders did not know which type of coffee they received.) As the competition progressed, the scores for each skateboarder were tracked. Match each description to its associated term below. ] The scores given to each competitor by the competition judges. |"Group A' with no caffeine. |The skateboarders taking part in the study. |The caffeinated cups of coffee (100mg of caffenine) that 'Group B' received. ] The decaffeinated cups of coffee (Omg of caffeine). | The cup of coffee (amount of caffine) given to the study participants. a.
