Answer:
Independent variable
Explanation:
In a scientific experiment, the variable that an experimenter varies or controls is called an independent variable. This variable has a direct impact on dependent variable.
In the question, Rachel wants to test how sunlight impacts plant growth over time. Now as sunlight impacts plant growth this means sunlight is an independent variable whereas the plants are dependent variable as the amounts of sunlight impact the plants. Also Rachel changes/varies or controls the amounts of sunlight to different sets of plants. Hence from the above definition of an independent variable it is clear that sunlight is an independent variable.

Dr. Swanson is using a Correlational design. Correlational designs are actively employed in forensic psychology research to establish the relationships between many sorts of factors that are meaningful.
<h3><u>What are correlational designs in psychology?</u></h3>
Correlational designs are non-experimental which means that none of the variables are manipulated or under the experimenter's control.
When it is important to investigate whether there is a relationship between specific elements and people's behavior, researchers often pick the correlational design. However, this design is inappropriate to identify the causes of this association.
Therefore, Dr Swanson in order to study the relation between mood and willingness to help a stranger, he is using a correlational design to establish the results. The result can be positive, negative or neutral based on positive, negative and no correlation between the variables respectively.
