If a variable is influenced by another variable, what is its classification?

A variable that is influenced by another variable is classified as a dependent variable. This terminology is used in experimental design to denote the variable that is observed or measured in response to changes made in another variable, known as the independent variable. Essentially, the dependent variable reflects the effects or outcomes that result from the manipulation of the independent variable.

For instance, if researchers are studying how different amounts of sunlight affect plant growth, the amount of plant growth would be the dependent variable because it depends on the varying amounts of sunlight, which is the independent variable. Thus, the classification as a dependent variable is essential in understanding the relationship between these two types of variables, allowing for clarity in data analysis and interpretation.
