This new statistic is an innovative in–depth way of further investigating a statistically significant post hoc Tri–Squared Test. MULTICOVA is an advanced and detailed statistical procedure for the internal testing of the outcomes of the mixed methods Tri–Squared Test (first introduced in the Journal on Mathematics, and detailed further in the Journal on Educational Technology, Journal on School Educational Technology, and in the Journal on Educational Psychology). MULTICOVA is an advanced statistical procedure; which is designed to measure the “Trichotomous Coefficient of Variation” of inputted and outputted Tri–Squared variables. The Trichotomous Coefficient of Variation is also a normalized measure of a trichotomous probability distribution or trichotomous frequency distribution. This new statistic is an innovative approach to the sequential series of advanced post hoc Tri–Squared Test statistical metrics. Multiple MULTICOVA equations are presented, as well as the entire process of advanced statistical Trichotomous Coefficient of Variation analytics that illustrate how to conduct this particular method of inquiry.
