# goodness of fit

- A statistical term used to indicate the correspondence between an observed distribution and a model or hypothetical mathematical distribution. In many statistical tests of significance the hypothetical or expected distribution is a model based upon there being no relationship between the dependent and independent variables . The tests then measure whether any observed deviation from the expected model may reasonably be accounted for by chance sampling variation, or whether it is sufficiently large to indicate a real difference, generalizable to the population from which the sample was taken. See also significance tests.
