WebThe meaning of DEGREE OF FREEDOM is any of a limited number of ways in which a body may move or in which a dynamic system may change. WebThe corrections affect the degrees of freedom of the F-distribution, such that larger critical values are used (i.e., the p-value increases). This is to counteract the fact that when the assumption of sphericity is violated, there is an increase in Type I errors due to the critical values in the F-table being too small. These corrections ...

In statistics, the number of degrees of freedom is the number of values in the final calculation of a statistic that are free to vary. Estimates of statistical parameters can be based upon different amounts of information or data. The number of independent pieces of information that go into the estimate of a parameter is called the degrees of freedom. In general, the degrees of freedom of an estimate of a parameter are e…
