Osler II Journal on Educational Psychology 2230 – 7141 6 4 36 41 Data Analysis, Education Science, Eduscience, Instrument, Investigative, Psychometrics, Trichotomy, Tri–Squared, and Statistics This monograph provides a psychological rational for the novel field of “Educational Science” and how it conducts in–depth research investigations first presented in an article by the author in the iManager Journal of Mathematics through the trichotomous analysis of the affective domain. Educational Science uses the innovative Total Transformative Trichotomy–Squared [Tri–Squared] Test as a means of informative inquiry. This novel approach to data analysis is a mixed methods research design that involves the holistic combination and comparison of qualitative and quantitative data. An example is provided of the process of creating trichotomous instruments that are an essential part of the Tri–Squared Test. February - April 2013 Copyright © 2013 i-manager publications.
