independent variable vs. dependent variable

Mathematics. a variable in a functional relation whose value determines the value or values of other variables, as x in the relation y = 3 x 2 . Compare dependent variable ( def 1 ).

Statistics. (in an experiment) a variable that is intentionally changed to observe its effect on the dependent variable. Compare dependent variable ( def 2 ), control variable ( def 1 ).

Mathematics. a variable in a functional relation whose value is determined by the values assumed by other variables in the relation, as y in the relation y = 3 x 2 . Compare independent variable ( def 1 ).

Statistics. (in an experiment) the event studied and expected to change when the independent variable is changed. Compare independent variable ( def 2 ), control variable ( def 1 ).
