If tests are reported, methodology unscienti c, data questionable. Observe that two events are systematically related. Basic: gaining theoretical understanding, i now we know so ^^ Anything that can have more than one level. Response - ex: number of questions answered. Mediating - something that connects 2 variables, ex: dealing of responsibility. Operational de nitions: de nition in terms of the technique the researcher uses to measure/manipulate. Problems: leave characteristics out, add extra characteristics, de nitions can impact conclusions. Validity: measuring what it is intending to measure.
