dependent variable in a mathematical equation or relationship between two or more variables, a variable whose value depends on those of others; it represents a response, behavior, or outcome that the researcher wishes to predict or explain.
extraneous variable a factor that is not itself under study but affects the measurement of the study variables or the examination of their relationships.
independent variable in a mathematical equation or relationship between two or more variables, any variable whose value determines that of others; it represents the treatment or experimental variable that is manipulated by the researcher to create an effect on the dependent variable.

de·pen·dent var·i·a·ble

in experiments, a variable that is influenced by or dependent on changes in the independent variable; for example, the amount of a written passage retained (dependent variable) as a function of the different numbers of minutes (independent variable) allowed to study the passage.

dependent variable

An objective finding measured in an experiment that is expected to change as a result of an experimental manipulation of the independent variable(s).

dependent variable
