Final answer:

In a scientific experiment, the dependent variable is what is measured as the outcome, the independent variable is plotted on the x-axis of a graph, and experimental studies involve manipulating variables.


Explanation:

In a scientific experiment, the dependent variable is the variable that is measured or observed as the outcome. It is the factor that is expected to change due to the manipulation of the independent variable. To ensure the validity of results, a controlled variable, also known as a constant, is kept consistent in a controlled experiment.

The independent variable is typically plotted on the x-axis of a graph in a scientific experiment to show its relationship with the dependent variable. This graphical representation helps visualize how changes in the independent variable impact the dependent variable.

Experimental studies involve manipulating the independent variable to observe its effects on the dependent variable. By controlling other variables (control variables), researchers can attribute any changes in the dependent variable solely to the independent variable manipulation.
