Question

Quizplus · Accepted Answer

Variables are factors that can be changed in an experiment and the experimenter expects them to change as a result of the experimental manipulation. Constants, on the other hand, are factors that are kept the same throughout an experiment. Conceptual definitions and operational definitions refer to the way a variable is defined, but do not necessarily indicate whether or not the experimenter expects the variable to change.
