If the correlation between separate administrations of the test is high (e.g. 0.7 or higher as in this Cronbach's alpha-internal consistency-table [6]), then it has good test–retest reliability. The repeatability coefficient is a precision measure which represents the value below which the absolute difference between two repeated test results ...
Unfortunately, there is no way to directly observe or calculate the true score, so a variety of methods are used to estimate the reliability of a test. Some examples of the methods to estimate reliability include test-retest reliability, internal consistency reliability, and parallel-test reliability. Each method comes at the problem of ...
[2]: 263 [3] He explained that he had originally planned to name other types of reliability coefficients, such as those used in inter-rater reliability and test-retest reliability, after consecutive Greek letters (i.e., , , etc.), but later changed his mind.
Cohen's kappa measures the agreement between two raters who each classify N items into C mutually exclusive categories. The definition of is =, where p o is the relative observed agreement among raters, and p e is the hypothetical probability of chance agreement, using the observed data to calculate the probabilities of each observer randomly selecting each category.
In statistics, inter-rater reliability (also called by various similar names, such as inter-rater agreement, inter-rater concordance, inter-observer reliability, inter-coder reliability, and so on) is the degree of agreement among independent observers who rate, code, or assess the same phenomenon.
Implicit measures, especially latency-based ones, typically struggle to achieve a satisfactory level of internal consistency and test-retest reliability. However, the IAT possess acceptable levels of both, with one review finding that internal consistency values of IAT's typically ranged from .7 to .9. [5]
Test–retest or retest or may refer to: Test–retest reliability; Monitoring (medicine) by performing frequent tests; Doping retest, of an old sports doping sample using improved technology, to allow retrospective disqualification
Reliability [ edit ] The NEQ has acceptable internal reliability ( Cronbach's alpha = 0.70) [ 4 ] and test–retest reliability ( r = 0.77–0.86 across 2–3 weeks).
