Answer:
Variable
Step-by-step explanation:
In the environment observed phenomena can be linked to a given set of possible outcomes. Thus, a variable can be understood as any quantity, quality or magnitude of a characteristic that can have several numerical values.
A variable can be understood as a classification or a measure; an amount that changes in each case or unit of study. A property in the study object that can be measured and enumerated, so the feature of an experiment that changes from one treatment to the next is called a variable.
