Dependent And Independent Variables
Variables used in an experiment or modelling can be divided into three types: "dependent variable", "independent variable", or other. The "dependent variable" represents the output or effect, or is tested to see if it is the effect. The "independent variables" represent the inputs or causes, or are tested to see if they are the cause. Other variables may also be observed for various reasons.

Famous quotes containing the words dependent, independent and/or variables:
“Almost everywhere we find . . . the use of various coercive measures, to rid ourselves as quickly as possible of the child within us—i.e., the weak, helpless, dependent creature—in order to become an independent competent adult deserving of respect. When we reencounter this creature in our children, we persecute it with the same measures once used in ourselves.”
—Alice Miller (20th century)
“I have defeated them all.... I was left with some money to battle with the world when quite young, and at the present time have much to feel proud of.... The Lord gave me talent, and I know I have done good with it.... For my brains have made me quite independent and without the help of any man.”
—Harriet A. Brown, U.S. inventor and educator. As quoted in Feminine Ingenuity, ch. 8, by Anne L. MacDonald (1992)
“The variables of quantification, ‘something,’ ‘nothing,’ ‘everything,’ range over our whole ontology, whatever it may be; and we are convicted of a particular ontological presupposition if, and only if, the alleged presuppositum has to be reckoned among the entities over which our variables range in order to render one of our affirmations true.”
—Willard Van Orman Quine (b. 1908)
