Answer:
Outcome variable (dependent variable)
Explanation:
In a scientific investigation, a DEPENDENT VARIABLE (also known as outcome variable) is the variable that is being measured. The dependent variable, as the name implies, responds to the changes made to the independent variable.
For example, in an experiment where the effects of different concentration of fertilizer is used to test plant growth (height), the HEIGHT OF THE PLANTS is the dependent variable because it is the variable being measured.
