spongellob and his bikini bottom pals have been busy doing a little research. read the description for each experiment and answer the questions. 1 - patty power mr. krabbbs wants to make bikini bottoms a nicer place to live. he has created a new sauce that he thinks will reduce the production of body gas associated with eating crabby patties from the krusty krab. he recruits 100 customers with a history of gas problems. he has 50 of them (group a) eat crabby patties with the new sauce. the other 50 (group b) eat crabby patties with sauce that looks just like new sauce but is really just mixture of mayonnnaise and food coloring. both groups were told that they were getting the sauce that would reduce gas production. two hours after eating the crabby patties, 30 customers in group a reported having fewer gas problems and 8 customers in group b reported having fewer gas problems. which people are in the control group? what is the independent variable? what is the dependent variable? what should mr. krabs conclusion be? why do you think 8 people in group b reported feeling better?

Answer

Brief Explanations:

  • Control group: Group B is the control group as they receive a placebo - like sauce (mixture of mayonnaise and food coloring) while Group A gets the new sauce.
  • Independent variable: The type of sauce (new sauce vs. placebo sauce) is what is being changed or manipulated.
  • Dependent variable: The number of customers reporting fewer gas problems is what is being measured and is affected by the type of sauce.
  • Mr. Krabs' conclusion: The new sauce appears to be effective in reducing gas problems since 30 out of 50 in Group A reported fewer gas problems compared to 8 out of 50 in Group B.
  • Reason for 8 in Group B feeling better: This could be due to the placebo effect, where people expect to feel better and so report improvement, or natural variation in their gas - producing processes.

Answer:

  • Which people are in the control group? Group B.
  • What is the independent variable? The type of sauce.
  • What is the dependent variable? The number of customers reporting fewer gas problems.
  • What should Mr. Krabs’ conclusion be? The new sauce seems to reduce gas problems associated with eating crabby patties.
  • Why do you think 8 people in group B reported feeling better? Placebo effect or natural variation.
