ABSTRACT
Up to this point, we have considered what we measure and how we should specify that target. In Part Two, we examine the technique of measuring. As implied earlier, each final index is obtained from a set of measurements, usually one measurement for the response to each stimulus. While the ultimate concern of personality measurement is with generalizing from observational data to unobserved phenomena identified with the construct, it is necessary also to evaluate the degree of confidence with which one can generalize from data derived by the measuring operation to hypothetical data that might be obtained at other times or with other stimuli or even with other orientations and settings.
