In psychological theory and application of statistics among the early, focus on measuring people's intelligence . Francis Galton is often considered the father of psychological statistics. He designed and applied a series of psychological tests. However, often the origin of psychological and statistical physics, psychology linked together. Psychological Statistics pioneer Charles Spearman mental physicist who studied under Wilhelm Wundt. Spearman designed to measure intelligence in the early methods. Psychological well-known statistician LL Thurstone has developed what came to be known as the law of comparative judgments of the measurement method, this method is considered and by Ernst Heinrich Weber and Gustav Fechner two mental physicists invented the measurement methods are closely linked. The development of their statistical measurement methods are now widely used in academic psychology statistics.In recent decades, is widely used statistical measure of psychological personality, attitudes and beliefs, education, production, and health-related fields. Observed characteristics of these remedial measures is very difficult, in theory circles, and many studies are dedicated to accurate definition of these concepts and their quantification. So this award is also gathered in the evaluation of these definitions and quantification of the doubt. A lot of criticism from the physics community and the social sciences of the militants, they believe that this measurement is often inaccurate, and were abused. But advocates believe that these psychological abuse of statistical data are often derived from statistical criteria for mental neglect. They also argue that the study of physics can not be observed in many of the attributes for example, the role of force and energy, but also rely on inference to achieve their performance was studied.
