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