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.

in·de·pen·dent var·i·a·ble

a characteristic being measured or observed that is hypothesized to influence another event or manifestation (the dependent variable) within a defined area of relationships under study; that is, the independent variable is not influenced by the event or manifestation, but may cause it or contribute to its variation. See: dependent variable.
