Final JeopardyFinal JeopardyRead the following experiment and then answer the question that Read the following experiment and then answer the question that follows.follows.Mr. Krabs created a secret ingredient for a breath mint that he thinks will “cure” the bad breath people get from eating crabby patties at the Krusty Krab. He asked 100 customers with a history of bad breath to try his new breath mint. He had fifty customers (Group A) eat a breath mint after they finished eating a crabby patty. The other fifty (Group B) also received a breath mint after they finished the sandwich, however, it was just a regular breath mint and did not have the secret ingredient. Both groups were told that they were getting the breath mint that would cure their bad breath. Two hours after eating the crabby patties, thirty customers in Group A and ten customers in Group B reported having better breath than they normally had after eating crabby patties.Questions: What is the independent variable? Dependent? Controlled variables?
Independent: Mr. Krab’s secret breath mint Independent: Mr. Krab’s secret breath mint ingredientingredient
Dependent: If the person’s breath improvesDependent: If the person’s breath improves Controlled: Same history of bad breath, eat the Controlled: Same history of bad breath, eat the
