It explains that merely measuring or questioning an individual's intentions or anticipated regret [1] changes his or her subsequent behavior. The mere-measurement effect has been demonstrated in multiple behavioural contexts both general and specific.
Measurement in psychology and physics are in no sense different. Physicists can measure when they can find the operations by which they may meet the necessary criteria; psychologists have to do the same. They need not worry about the mysterious differences between the meaning of measurement in the two sciences (Reese, 1943, p. 49). [9]
Psychometrics deals with measurement of psychological attributes. It involves developing and applying statistical models for mental measurements. [2] The measurement theories are divided into two major areas: (1) Classical test theory; (2) Item Response Theory. [3]
Many large-scale clinical tests are normed. For example, scores on the MMPI are rescaled such that 50 is the middlemost score on the MMPI Depression scale and 60 is a score that places the individual one standard deviation above the mean for depressive symptoms; 40 represents a symptom level that is one standard deviation below the mean.

Applied Psychological Measurement is a peer-reviewed academic journal published by SAGE Publications. The journal covers research on methodologies and research on the application of psychological measurement in psychology and related disciplines, as well as reviews of books and computer programs.
The Affective Slider is an empirically validated digital scale for the self-assessment of affect composed of two slider controls that measure basic emotions in terms of pleasure and arousal, [6] which constitute a bidimensional emotional space called core affect, that can be used to map more complex conscious emotional states.
understanding the hidden meaning of numbers through analytical and critical thinking (e.g., Freakonomics [10]); rounding (understanding reasons for rounding large numbers and limitations in comparisons); choosing measurement units to make sense for a given situation; solving real-life problems involving percentages and decimal portions;
The values scale outlined six major value types: theoretical (discovery of truth), economic (what is most useful), aesthetic (form, beauty, and harmony), social (seeking love of people), political (power), and religious (unity). Forty years after the study's publishing in 1960, it was the third most-cited non-projective personality measure. [4]
