F Test

Carlos Hilado Memorial State College Fortune Towne Campus F Test ( Sceffe Test) nonice By: Haironezza E. Abdullah MBA 201 The F Test We made an F running play antecedently when dischargeing he difference between deuce variables to attend to whether or not we should pool them. The analysis of sectionalisation control board is evaluated by making the following F campaign: F= tight full-blooded for between groupsmean square for with in groups =82.516.3 = 5.06 F ratios are interpreted by employment of the F shelve. This table is entered with the number of degrees of freedom for the great mean square crossways the top and with the number of degrees of freedom for the lesser mean-square on the go forth hand side. For this problem, we go everywhere to 2 and down to 18. In the location we observe that the hold dear of F needed for the significance at the 5 part microscope stage is 3.55. Since our obtained F is greater than this, we reject the null conjecture of no difference among these substance at the 5 percent point. To summarize the above in a decision puzzle we have. Ho:?1=?2=?3 H1:not Ho a: .05 DR: Reject Ho if Fobs>3.55;otherwise do not reject. There are times when the value of the F ratio will be less than 1. There is no point in solving for the value of such a ratio, since such ratios are not large. Test after the T test Since in the previous problem we found that there were prodigious differences between the means, the next task is to see where the difference or differences are. Winer (1921) summarized half-dozen different methods for doing this. Some of these methods are more rigorous than the others and mould low the probability of making a Type I error. nonpareil of these tests (Sceffe, 1957) will be introduced here. Although this is one of the more rigorous methods, it is as well as one of the easier ones to compute. The following represents the test results of three groups of students. Table 1 A| B| !
