Patrick believes that fish that eat food exposed to microwaves will become smarter and would be able to swim through a maze faster.

He feeds the special food to 10 fish and gives regular food to 10 others. After 1 week, he has the fish swim through the maze again and record the times for each. What is his independent variable?

Mr. Krabbs 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 tests 100 customers by having 50 (Group A) eat patties with the new sauce. The other 50 (Group B) eat patties with a fake "sauce". Neither group knows who has the real sauce. Two hours later 30 customers in group A reported having fewer gas problems and 8 customers in group B reported having fewer gas problems. What is the independent variable?
