In psychology and sociology, the Thurstone scale was the first formal technique to measure an attitude. It was developed by Louis Leon Thurstone in 1928, originally as a means of measuring attitudes towards religion. Today it is used to measure attitudes towards a wide variety of issues.
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]
In modern-day terminology, it is more aptly described as a model that is used to obtain measurements from any process of pairwise comparison. Examples of such processes are the comparisons of perceived intensity of physical stimuli , such as the weights of objects, and comparisons of the extremity of an attitude expressed within statements ...
The term sociometry relates to its Latin etymology, socius meaning companion, and metrum meaning measure. Jacob Moreno defined sociometry as "the inquiry into the evolution and organization of groups and the position of individuals within them."
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]
Borsboom discusses the importance of psychological testing and hence the importance of measurement models in psychometrics. He describes such models as “local philosophies of science” and goes on to discuss several major “global” philosophies of science; logical positivism, instrumentalism, and social constructivism all of which he describes as “anti-realist” to contrast with ...
The table shown on the right can be used in a two-sample t-test to estimate the sample sizes of an experimental group and a control group that are of equal size, that is, the total number of individuals in the trial is twice that of the number given, and the desired significance level is 0.05. [4] The parameters used are:
Mathematical psychology is an approach to psychological research that is based on mathematical modeling of perceptual, thought, cognitive and motor processes, and on the establishment of law-like rules that relate quantifiable stimulus characteristics with quantifiable behavior (in practice often constituted by task performance).
