Abstract
Large and complex experiments highlight the need to develop robust methods for calculating effectiveness. This report develops a method for calculating the measure of effectiveness (MOE) with bi-polar scales and vector algebra, called the vector method. The method treats each datum as an element in a vector rather than a number in a distribution. Thus, the resultant vector represents a vector sum of measured values along bi-polar scale dimensions. This vector is projected onto a reference vector that represents the ideal situation, using the Euclidean product. The projection is the degree to which the measured vector matches the reference vector – which is the working definition for a MOE.
