Document Summary
Measurements: assignment of numbers to objects or events according to specific rules. Fundamentals of measurement conceptual variables ideas that form the basis of a research hypothesis. Measured variables: consist of numbers that represent the conceptual variables. Operational definition: precise statement of how a conceptual variable is turned into a measured variable. No single operational definition of a given conceptual variable can be considered the best converging operations: when the same conceptual variable is measured using different measures, can get a fuller and better measure of it. Expectation that changes in the conceptual variables will cause changes in the corresponding measured variables. Measured variables: used to draw inferences about the conceptual variables. Basic assumption involved in testing the research hypothesis if the research hypothesis is correct, and if the measured variable are adequate then: a relationship between the two measured variables will be observed.
