Definition of random variable in US English: random variablenoun Statistics A quantity having a numerical value for each member of a group, especially one whose values occur according to a frequency distribution. Also called variate Example sentencesExamples - Chernoff bounds are the most useful for sums of bounded independent random variables.
- For example, the correlation coefficient between two random variables is zero not only in the case of independence, but whenever there is no linear association.
- An alternative approach is to consider allelic frequencies as random variables, whose distribution depends on some parameters of the population model.
- In this case, the numbers of people wanting to buy tickets at a given fare are random variables.
- The error terms from the regression equations are modeled as random variables with a probability distribution.
