Question

A doctor treats a patient with a skin condition with different creams to see which is most effective. What is the independent variable?
1. Skin Creams
2. Skin Conditions

Answer 1

Answer:

1. Skin Creams

Explanation:

An independent variable is the only variable that is changed while the rest is kept the same. In this setup, the doctor is using different creams on the same patient with the same skin condition so the independent variable is the skin cream and not the skin condition.
