Probability is used in mathematical statistics to study the sampling distributions of sample statistics and, more generally, the properties of statistical procedures. A statistic is a random variable that is a function of the random sample, but not a function of unknown parameters.

Further examining the data set in secondary analyses, to suggest new hypotheses for future study. While one can not "prove" a null hypothesis, one can test how close it is to being true with a power testwhich tests for type II errors.

Are policies that reduce governmental debt also associated with reduction in quality of life? Sampling theory is part of the mathematical discipline of probability theory.

Furthermore, an estimator is said to be unbiased if its expected value is equal to the true value of the unknown parameter being estimated, and asymptotically unbiased if its expected value converges at the limit to the true value of such parameter. The psychophysicist Stanley Smith Stevens defined nominal, ordinal, interval, and ratio scales.
