The F Distribution and the F-Ratio Introduction to Statistics
WebBecause of the generality of such tests, the F-ratio distribution is used in many fields, including economics, psychology, pharmacy, engineering, medicine, and manufacturing. RandomVariate can be used to give one or more machine- or arbitrary-precision (the latter via the WorkingPrecision option) pseudorandom variates from an F-ratio distribution. WebThe first one gives critical values of F at the p = 0.05 level of significance. The second table gives critical values of F at the p = 0.01 level of significance. 1. Obtain your F-ratio. This has (x,y) degrees of freedom associated with it. 2. Go along x columns, and down y rows. The point of intersection is your critical F-ratio. 3.
