Document Summary
Directional- group 1 is better than group 2. Non directional- there will be some diff between the two or some relationship between the variables. Empiricism- knowledge collected through the senses, observation, experience. Operational definition- define the variable by the means used to measure it. Specifically state how you are going to measure it. A good theory is is consistent with known facts is logically [internally] consistent is parsimonious is falsifiable [there is some possible outcome that would disprove the hypothesis] is testable [generates testable hypotheses] Hypothesis- a testable statement. a prediction about what will happen with the variables of interest. Construct-a construct is a hypothetical variable which is not directly observable. Parallel or alternate forms - multiple sets constructed in the same way. If a measure is valid, it must also be reliable. Magnitude numbers have an inherent order from smaller to larger. Equal intervals the difference between units is the same anywhere on the scale.
