Final answer:
In the given scenario, the number of students in a class (s) is the independent variable, while the number of desks needed (d) is the dependent variable. The independent variable is presumed to cause a change in the dependent variable.
Step-by-step explanation:
The student is asking about the relationship between two variables: the number of students in a class (s) and the number of desks needed (d). In this context, the independent variable (IV) is typically the one that is believed to cause or influence the other variable. It is the starting point, or the cause, within the relationship. On the other hand, the dependent variable (DV) is generally thought to be the result, or effect, due to changes in the independent variable.
For this particular example:
- The independent variable would be the number of students in a class (s), since this is what is presumed to influence or necessitate a certain number of desks.
- The dependent variable would be the number of desks needed (d), as this is expected to vary in response to the number of students.
So, as the number of students (s) increases, the number of desks needed (d) also increases. This relationship assumes that each student will need their own desk, hence the direct dependence of desks on the number of students.
