Document Summary

Variables vs. constants: measured and manipulated variables, from conceptual variable to operational definition. Measured and manipulated variables (cid:190) measured variables are observed and recorded. (cid:190) manipulated variables are controlled. Some variables can be either manipulated or measured. Defines the operations or techniques the researcher will use to measure or manipulate a variable. Construct: an abstract concept that must be translated into concrete forms of observation or manipulation: example: hunger, intelligence, aggression (cid:190) many ways to operationalize the same construct. Non experimental: no manipulation of variables, description of behavior. Frequency claims describe a particular rate or degree of a single variable. Association claims argue that one level of a variable is likely to be associated with a particular level of another variable. Association claims involve at least two measured variables.
