enEnglish
Probability definition: The study of chance processes or the relative frequency characterizing a chance process.
Probability definition: A measure of the expectation of the occurrence of a particular event.
Probability Learning definition: Usually refers to the use of mathematical models in the prediction of learning to perform tasks based on the theory of probability applied to responses; it may also refer to the frequency of occurrence of the responses observed in the particular study.
Probability Theory definition: The branch of mathematics dealing with the purely logical properties of probability. Its theorems underlie most statistical methods. (Last, A Dictionary of Epidemiology, 2d ed)
Significance Level definition: The probability of a type I error of a statistical hypothesis test, a fixed probability of wrongly rejecting the null hypothesis H0, if it is in fact true. It is set by the investigator in relation to the consequences of such an error. The often chosen significance level is 5%.
F definition: Used to describe the quotient of two c2 random variables. The F-distribution has two parameters n1 and n2, which are the numbers of degrees of freedom of the numerator and denominator variable respectively. The relationship to mean m and variance s2 are: m = n2 / (n2 - 2) and s2 = (2 n2 (n2 + n1 - 2)) / (n1 (n2 - 2)2 (n2 - 4)).
beta definition: The beta-distribution is used for data that is bounded on both sides and may or may not be skewed (e.g., occurs when probabilities are estimated.) Two parameters a and b are available to adjust the curve. The mean m and variance s2 relate as follows: m = a/ (a + b) and s2 = ab/((a + b)2 (a + b + 1)).
