Question

mr krabs wants to make a nicer place to live. he has created a new sauce that he thinks will reduce the 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 mayonnaise and food coloring. both groups were told the sauce that would reduce gas production. two hours after eating, customers in group a reported having fewer gas problems and customers in group b reported having fewer gas problems.

Explanation:

La variable independiente es lo que se manipula en un experimento. Aquí, es la clase de salsa que se da a los clientes. La variable dependiente es lo que se mide, en este caso, la cantidad de problemas de gases. El grupo experimental es el que recibe la intervención real (salsa nueva), es decir, el grupo A. El grupo de control es el que recibe un placebo (salsa falsa), es decir, el grupo B.

Answer:

• Variable independiente: el tipo de salsa
• Variable dependiente: la cantidad de problemas de gases
• Grupo experimental: grupo A
• Grupo de control: grupo B
