b. dependent variable =
c. control =

Explanation:

Problem 6:

• Independent Variable: The factor that is manipulated. Here, the treat flavors (chicken or beef) are what's being changed to see the kitten's preference.
• Dependent Variable: The factor that is measured/observed. The kitten's preference (which treats it eats first or more of) depends on the flavor.
• Control: Elements kept constant to ensure a fair test. The number of treats (10 of each) and the setup (bowls, environment) are controlled, and repeating for 3 days helps consistency.

• Independent Variable: The factor manipulated (wrapping the phone in aluminum foil or not).
• Dependent Variable: The factor measured (number of dropped calls), as it depends on whether the phone is wrapped.
• Control: Elements kept constant (phone model, location - bedroom, number of calls made in each condition) to ensure a fair test.

Answer:

a. Independent Variable = Treat flavors (chicken, beef)
b. Dependent Variable = Kitten's treat preference (which treats it eats first/more)
c. Control = Number of treats (10 of each), experimental setup (bowls, environment), repeating for 3 days
