Question

Jorge has made the hypothesis that the more he feeds a mouse, the shinier its fur will be, because the mouse will be healthier.

What should be the independent variable in an experiment testing this hypothesis?


A. how shiny each mouse's fur is

B. how much each mouse weighs

C. the type of food he feeds each mouse

D. the amount of food he feeds each mouse

Answer 1

The correct answer is D. The amount of food he feeds each mouse

Step-by-step explanation:

In research, the independent variable refers to the variable or factor that is manipulated by the researcher. Besides this, the independent variable affects the dependent variable or factor being studied. This implies in the case presented, the dependent variable is how shiny mice's fur is because this is the variable being studied; on the other hand, the independent variable is the amount of food Jorge feeds to each mouse because this is the factor Jorge would manipulate or change to prove if the amount of food has an effect on the fur of mice.
