Final answer:
In an experiment, the variable manipulated by the researcher is the independent variable. The dependent variable is the outcome that is measured, which depends on the changes of the independent variable.
Step-by-step explanation:
In an experimental method, the variable that the experimenter changes or manipulates is referred to as the independent variable. This is the condition or factor that the researcher manipulates to see its impact on the dependent variable.
On the other hand, the variable that is measured at the end of the experiment is referred to as the dependent variable. This variable depends on the changes made to the independent variable. In other words, the dependent variable is the outcome that the researcher is interested in measuring after changing the independent variable.
For instance, if a researcher is investigating the effect of different amounts of sunlight (independent variable) on the growth of a particular plant species (dependent variable), he/she would manipulate the amount of sunlight the plant receives and measure the plant's growth as a result.
