Document Summary
The process of creating measurable concrete variables from abstract concepts. Extend the senses (empirical-much less sensitive to change than senses; yields more consistent between findings ex: thermometer =more accurate temp than someone just touching a pole and gauging that way) Tends to be more of a concern for quantitative researchers. Both involve conceptualization (the process where you think through the meaning of the construct) and operationalization (when you take the conceptual def and turn into different measurement techniques) ** see pg 107 in textbook for abstract construct to concrete measure diagram. Empirical observations working ideas concepts generalizations/theories (**not every qualitative researcher will use this process more flexibility) Reliability: the consistency or dependability of a meansure. Validity: truthfulness of a measure (**no perfect validity of reliability they are ideals) Results should be similar after re-test at a later time. If two different researchers test the same thing they should both end up with he same or very similar results.
