Document Summary
Measurement is a process of using indication to represent constructs. Indicator: a perceptual feature of the world (things we perceive) Constructs: a perceptual template that serves to organize our experiences of the world (have in your head, no variable, mental entities) Score: a number (cm cubed) based on the three indicators. Indicator: amount of time to take to name all the words. An issue of whether the number of indicators is sufficient to represent the. Usually addressed by having experts review the indicators as a part of the primary design of an instrument. Is a practical way of describing the relationship between constructs and indicators. Convergent evidence an instrument yields scores that correlate with a measure of the same construct or related construct. Discriminant evidence an instrument yields scores that do not correlate with a measure of a different construct. Arrow pointing both ways between two things. In most ways my life is close to my ideal. (5)
