A |
|---|
axioms of probabilitySee Kolmogorov axioms [Deutsch] | |
C |
|---|
Central tendencyA typical value for a distribution. [Deutsch] | |
coin tossIf it is a fair coin, then a coin toss can be regarded as random experiment. [Deutsch] | |
complementThe complement of set A contains everything that is not in the set A [Deutsch] | |
conditional probabilityThe measure of the probability of an event occurring, given that another event occurred. [Deutsch] | |
continuous variableCan take an uncountable set of values. [Deutsch] | |
D |
|---|
dependent variableThe value of a dependent variable depends on the value(s) of independent variable(s). [Deutsch] | |
descriptive statisticsSummaries of a given data set, which can be either of an entire population or a sample of a population. [Deutsch] | |
deterministic eventAn event in which we can predict what will happen according to some model or set of equations. Once we know the starting conditions, we know the endpoint [Deutsch] | |
discrete variableThe number of values is either finite or countably infinite. [Deutsch] | |
disjoint setsAlso: disjoint sets. Two sets are disjoint when they have no element in common. [Deutsch] | |
DispersionAlso: Variability. The extent to which a distribution is spread. [Deutsch] | |
E |
|---|
expectation valueAlso: expected value. Of a discrete random variable: the probability-weighted average of all possible values. Of a continuous random variable: the integral of the random variable with respect to ist probability measure. [Deutsch] | |
I |
|---|
identically distributed random variableAlso: uniformly distributed variable. All outcomes of a random experiment are equally likel. [Deutsch] | |
independent variableA change in the independent variable causes a change in the dependent variable. [Deutsch] | |
inferential statisticsUses a random sample taken from a population to make inferences about the population. [Deutsch] | |
P |
|---|
pairwise disjointAny two sets are two disjoint [Deutsch] | |
power set (of S)contains all the subsets of S [Deutsch] | |
probabilityA numerical description of how likely an event is to occur. The value range is between 0 and 1. [Deutsch] | |
probability distributionA statistical function that describes all the possible values that a random variable can take. [Deutsch] | |
R |
|---|
random experimentWhen we cannot predict what will happen in a specific event, then this event can be regarded as random experiment. We may know the underlying process but not the outcome. [Deutsch] | |
random variableA variable whose values depend on the outcome of a random experiment. [Deutsch] | |
S |
|---|
sample spaceDenoted as Omega. The set of all possible outcomes of a random experiment. [Deutsch] | |
setA well-determined collections of objects. [Deutsch] | |
T |
|---|
theory of probabilityTreats the concept of probability through a set of axioms (e.g., Kolmogorov axioms). [Deutsch] | |
U |
|---|
unionThe union of a collection of sets is the set of all elements in the collection [Deutsch] | |
