In a three-dimensional plot where two factors determine the outcome, which axis would display the dependent variable (the outcome)?
Correct Answer:
Z-axis
Explanation:
When two factors determine an outcome in a 3D plot, those two factors are laid out on two axes (typically the X and Y axes), while the third dimension represents the outcome itself. The dependent variable is shown on the vertical axis, the Z-axis, so you can see how the result changes as you vary the two inputs. Time would only be used as an axis if time were one of the factors, which isn’t implied here.
