Classical test theory is an influential theory of test scores in the social sciences. In psychometrics, the theory has been superseded by the more sophisticated models in item response theory (IRT) and generalizability theory (G-theory).

The United Kingdom driving test is a test of competence that UK residents take in order to obtain a full Great Britain or Northern Ireland (car) driving licence or to add additional full entitlements to an existing one. [1] Tests vary depending on the class of vehicle to be driven. In Great Britain it is administered by the Driver and Vehicle ...
Log–log graph of the probability that a number starts with the digit(s) n, for a distribution satisfying Benford's law. The points show the exact formula, P(n) = log 10 (1 + 1/n). The graph tends towards the dashed asymptote passing through (1, log 10 e) with slope −1 in log–log scale. The example in yellow shows that the probability of a ...

Likelihood-ratio test. In statistics, the likelihood-ratio test is a hypothesis test that involves comparing the goodness of fit of two competing statistical models, typically one found by maximization over the entire parameter space and another found after imposing some constraint, based on the ratio of their likelihoods.
Random walk hypothesis test by increasing or decreasing the value of a fictitious stock based on the odd/even value of the decimals of pi. The chart resembles a stock chart. Whether financial data can be considered a random walk is a venerable and challenging question. One of two possible results are obtained, the data does fall under random ...
Rasch model. The Rasch model, named after Georg Rasch, is a psychometric model for analyzing categorical data, such as answers to questions on a reading assessment or questionnaire responses, as a function of the trade-off between the respondent's abilities, attitudes, or personality traits, and the item difficulty. [1][2] For example, they may ...
The hazard perception test is administered as part of the theory test and is taken immediately after the multiple-choice questions. Learner drivers can sit the test from the age of 17. Those on the higher rate component of Disability Living Allowance are able to take the test at 16. For the purposes of the test, a "developing hazard" is ...
