Abstract: Colleges and Universities in the United States use Student Ratings of Instruction [SRI] for course evaluation purposes. Thisresearch investigation is the second part of a post hoc study that psychometrically examines the reliability and validity ofthe items used in the SRI instrument. The sample under analysis consisted of the responses to 56,451 total items extractedfrom 7,919 distributed Student Ratings Instruments delivered online during the 2012 academic year. The 7,919 SRIs weredelivered electronically at a Historic Black College and University [HBCU] to students who completed the 2012 springsemester SRI survey (the SRI is a measurement instrument used by students to assess instruction in courses in which they arecurrently enrolled). The post hoc application of the Tri–Squared Test is used to analyze the results of an earlier studyconducted with Cronbach's Alpha Reliability Model. Three SRI factors were analyzed: Efficacy, Validity, and Reliability. Theadditional application of Goodman & Kruskal's Lambda, and Principal Component Factor Analysis with Varimax Rotationalso found strong construct validity within the SRI. This research is the continuation of research conducted with theTri–Squared statistical measure which is first introduced in i-manager's Journal of Mathematics.
