Answer:

d. dependent

Explanation:

In research, we usually have two different types of variables:

  • The independent variable is the one that the researchers can control and that will have an effect on another variable.
  • The dependent variable is the one that cannot be controlled and that is affected by the independent variable. Researchers observe this variable to see how it changes. This is the variable that will be tested or measured.

In this example, Drs. French and Heinz are conducting an experiment on the effects of sugar on consumers' perception of condiment flavor. We can see that they think sugar will affect the perception of condiment flavor. Since this variable is the one that will be affected and that will later be measured on a variety of scales we can say that flavor perception is the dependent variable.
