independent variable

n.
1. Mathematics A variable whose value determines the value of other variables.
2. Statistics A manipulated variable in an experiment or study whose presence or degree determines the change in the dependent variable.

independent variable

n
1. (Mathematics) Also called: argument a variable in a mathematical equation or statement whose value determines that of the dependent variable: in y = f(x), x is the independent variable
2. (Statistics) statistics Also called: predictor the variable which an experimenter deliberately manipulates in order to observe its relationship with some other quantity, or which defines the distinct conditions in an experiment. See also experimental condition

in′depend′ent var′iable


n.
a variable in a functional relation whose value determines the value or values of other variables, as x in the relation y= 3x2.

in·de·pen·dent variable

(ĭn′dĭ-pĕn′dənt)
Mathematics
A variable whose value determines the value of other variables. For example, in the function y = x - 4, x is the independent variable because its value determines the value of y.
