The Rorschach Performance Assessment System (R-PAS) [1] [2] is a scoring and interpretive method to be used with the Rorschach inkblot test. [3] This system is being developed by several members of the Rorschach Research Council, a group established by John Exner to advance the research on the Comprehensive System, the most widely used scoring system for the Rorschach.
Rorschach performance assessment system (R-PAS) is a scoring method created by several members of the Rorschach Research Council. They believed that the Exner scoring system was in need of an update, but after Exner's death, the Exner family forbade any changes to be made to the Comprehensive System. [ 58 ]
His test was widely popular but also critiqued. After his death, multiple other Ink Blot tests were formed. Some of these new tests include: The Howard Ink Blot Test, Holtzman inkblot technique, and Rorschach II Ink Blot Test. Under the guidance of Rorschach, Hans Behn-Eschenburg developed 10 similarly designed inkblots to Rorschach's in 1920.
In statistical hypothesis testing, a two-sample test is a test performed on the data of two random samples, each independently obtained from a different given population. The purpose of the test is to determine whether the difference between these two populations is statistically significant .
The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample. In practice, the sample size used in a study is usually determined based on the cost, time, or convenience of collecting the data, and the need for it to offer sufficient statistical power. In complex studies ...
If the null hypothesis is true, the likelihood ratio test, the Wald test, and the Score test are asymptotically equivalent tests of hypotheses. [8] [9] When testing nested models, the statistics for each test then converge to a Chi-squared distribution with degrees of freedom equal to the difference in degrees of freedom in the two models. If ...
Bruno Klopfer (1 October 1900 – 23 October 1971) was a German psychologist, born in Bavaria.. He had a profound impact on the development of psychological personality testing, and was an important pioneer and innovator in the development, scoring and popularization of projective techniques, especially the Rorschach inkblot test.
