In an equation, there are two types of variables: independent and dependent. These values represent mathematical tools that are used in an experiment. Independent and dependent variables allow a researcher to maintain control, measure results, and draw accurate conclusions. The basic definition of independent and dependent variables is universal in both science and math. However, the way the variables are used differs depending on whether you are conducting a scientific experiment, performing a math problem, or studying statistics.
