Document Summary
In normally stated in terms of a relationship between the independent variable and dependent variable . Ex: the greater the alienation the more hateful the experience of work. Establishing causality requires: one has eliminated the effects of all extraneous variables a. In the case of experimental research, this is done by holding the extraneous variables constant. In the case of survey research, this is done statistically through the selection of sub- samples: Ideally, the subjects that made up the sub-sample are identical with the exception of the variables being tested. Levels of data: nominal- refers to observations that are qualitatively different, ordinal- refers to observations that can be ranked. Ex: agree, slightly agree, disagree, and strongly disagree. Interval- refers to observations that can not only be ranked, but the interval between the rankings can be qualified. The rule: operationalize the variables so to attain the highest level of data. Used to fudge the results in the media.
