Direction refers to negative or positive: advantages: Can be used to make predictions about variables. Relationships may be die to a their unmeasured variable. If variable a is causing changes on variable b - come up with an expirement: three essential characteristics: Measure whether this variable produces changes in another variable. Control for other factors that might influence results: independent vs. dependant variable. Independent variable - the fact that is manipulated or controlled by the experi- menter. Dependant variable - the factor that is measured by the experimenter and that may be influenced by the independent variable.
