The name of this formula stems from the fact that is the twentieth formula discussed in Kuder and Richardson's seminal paper on test reliability. [1] It is a special case of Cronbach's α, computed for dichotomous scores. [2] [3] It is often claimed that a high KR-20 coefficient (e.g., > 0.90) indicates a homogeneous test. However, like ...
Further, the logit (log odds) of a correct response is () (assuming =): in particular if ability θ equals difficulty b, there are even odds (1:1, so logit 0) of a correct answer, the greater the ability is above (or below) the difficulty the more (or less) likely a correct response, with discrimination a determining how rapidly the odds ...
The term "sport psychology" was first used back in 1900 by Pierre de Coubertin. The field saw notably contributions from the pioneers in Wundt and de Coubertin in the early 1900s. [6] The birth of sport psychology in Europe happened largely in Germany. The first sport psychology laboratory was founded by Dr. Carl Diem in Berlin, in the early ...
Non-parametric tests such as chi-squared test, Mann–Whitney test, Wilcoxon signed-rank test, or Kruskal–Wallis test. [ 16 ] are often used in the analysis of Likert scale data. Alternatively, Likert scale responses can be analyzed with an ordered probit model, preserving the ordering of responses without the assumption of an interval scale.
The Draw-a-Person test (DAP, DAP test), Draw-A-Man test (DAM), or Goodenough–Harris Draw-a-Person test is a type of test in the domain of psychology. It is both a personality test, specifically projective test, and a cognitive test like IQ. The test subject uses simple art supplies to produce depictions of people.
Before he created the inventory, Strong was the head of the Bureau of Educational Research at the Carnegie Institute of Technology. Strong attended a seminar at the Carnegie Institute of Technology where a man by the name of Clarence S. Yoakum introduced the use of questionnaires in differentiating between people of various occupations.
Mental toughness is a measure of individual psychological resilience and confidence that may predict success in sport, education, and in the workplace. [1] The concept emerged in the context of sports training and sports psychology, as one of a set of attributes that allow a person to become a better athlete and able to cope with difficult training and difficult competitive situations and ...
