Answer 1

The independent variable is 'year' because it is manipulated by the experimenter, while the dependent variable is the 'number of flu cases diagnosed' because it is measured to see the effect of the independent variable.

Step-by-step explanation:

The independent variable is "year" because it is the variable that is manipulated or controlled by the experimenter. In this case, the year represents the passage of time, which is deliberately chosen to observe any changes in the number of flu cases diagnosed. On the other hand, the dependent variable is the "number of flu cases diagnosed" because it is what the researcher measures to see how much effect the independent variable had. The number of flu cases diagnosed is expected to change as a function of the year, which makes it the dependent variable.
