Facets:
value: to every sample
type: TRANSITIVE-OBJECT
Source sentences:
text: Thus, the value of p̂ is a random variable, and must have a mean and standard deviation.
text: The value of the sample sum or sample mean is random, because it depends on the random sample.
text: But since there is randomness to every sample obtained, the value of p̂ will vary from sample to sample.
text: If the values instead were a random sample drawn from some large parent population (for example, they were 8 students randomly and independently chosen from a class of 2 million), then one often divides by 7 (which is n − 1) instead of 8 (which is n) in the denominator of the last formula.
text: When the observations from the sample ,..., are the realizations of random variables ,..., , then the value taken by the empirical distribution at a given point can also be regarded as a random variable.
text: Because the value of x {\displaystyle x} that defines the left tail or right tail event is a random variable, this makes the p-value a function of x {\displaystyle x} and a random variable in itself; under the null hypothesis, the p-value is defined uniformly over [ 0 , 1 ]
