Experiment 3: Krusty the Clown was told that a certain itching powder
(designed to make people itch as a joke) was the newest best thing on the
market. It even claims to cause 50% longer lasting itches. Interested in this
product, he buys the itching powder and compares it to his usual product. One
test subject (A) is sprinkled with the normal original itching powder, and another
test subject (B) was sprinkled with the new Experimental itching powder.
Subject A reported having itches for 30 minutes. Subject B reported having by
itches for 60 minutes.
What’s the experimental group?

The subject B would be the experimental group in this scenario. This is because they were subjected to the new itching powder to test if it was better than his regular one and that would make the subject A the control group. When he compared the two results he saw that the experiment was a success and that the new powder really did work but instead of 50% longer lasting itches, it had 100% longer lasting itches since 60 is 100% more than 30 minutes and 50% is 45minutes.
