If time is one of the variables used in an experiment, the scientist usually decides at which time points he/she wants to take measurements of the other variable. because time is used in this manner in experimental protocols, it is considered the variable and is always plotted on the .3. if time is one of the variables used in an experiment, the scientist usually decides at which time points he/she wants to take measurements of the other variable. because time is used in this manner in experimental protocols, it is considered the variable and is always plotted on the .

The correct answer is - 1) independent 2) X.

Explanation:

independent variable is the variable or the factor that is altered or made constant or controlled to see or test the effect on the dependent variable in an experiment. Time is used in the experimental protocols in such a manner that it is considered as the independent variable.

In a graph, time is always plotted in the X-axis as independent variables are normally plotted horizontally in a graph.

Thus, the correct answer is option - 1) independent 2) x.
