Kayla is designing an experiment to see if a new drug improves people's hearing ability. She measures the hearing ability of 100 participants. She then gives 50 people the drug and 50 people a placebo for one month. She then measures their hearing ability at the end of the month to see if there is a change. What is her IV, DV, and Control Group?
IV: Drug vs. No Drug DV: Change in Hearing Ability Control Group: Placebo Group

Nasir is investigating the effect of nutrition on muscle mass. He asks three friends to participate in his study. The first friend eats only meat for one week and works out every day. The second friend eats only vegetables for one week and works out every day. The third friend eats only carbohydrates for one week and never works out. Nasir then measures each friend's muscle mass. What are two ways Nasir could improve his experiment?
Measure the muscle mass before the experiment Make sure all the friends work out the same amount Use more than three test subjects Make sure all the friends have the same muscle mass before the experiment Conduct the experiment for more than one week

Damar is testing a new weight loss drug. He has 6 participants. He gives the drug to participants 1-3 and he gives the placebo to participants 4-6. Participants 1-3 initially have weights of 195, 200, and 205 lbs. Participants 4-6 originally have weights of 120, 140, and 160. After one month, the average weight of the experimental group is 205 and the average weight of the control group is 138. By how much did the average weight of each group change AND did the drug work? Explain.
Experimental group gained an average of 5 pounds Control group lost an average of 2 pounds The drug did not work
