Answer:
Dependent
Step-by-step explanation:
In research, we 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 control 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 Professor Nguyen wants to study the impact of mood on reading comprehension. In other words, he's trying to see the effect mood has on reading comprehension. We can see that reading comprehension will be the variable that is being affected and that will also be measured (using a reading comprehension score), therefore this would be considered the dependent variable.
