Document Summary
Theories formed together = concepts but how do we form concepts: need to consider which schema works best for comparative research (capacity to be used for comparative) Interval: ranking with meaningful units, temperature; ig; sat, a level of measurement describing a variable whose attributes are rank-ordered and have equal distances b/w adjacent attributes, 4. And part of this is looking at the extent of its validity. What three issues do researchers address when measuring the validity of their research design: quality of observations, representativeness of survey participants, causation (can you say with confidence that this one variable x caused y) Is it valid: face validity = a question of consensus. Construct validity: associations b/w our concept that we"re measuring and other outcomes. You can look at the other responses, sometimes there"s a plausible response for the missing one: assign numbers randomly, you can model the outcome or variable for which the outcome is missing.
