F Test

Carlos Hilado Memorial State College Fortune Towne Campus F Test ( Sceffe Test) chance on By: Haironezza E. Abdullah MBA 201 The F Test We made an F rill antecedently when assaying he difference between dickens variables to attend to whether or not we should pool them. The analysis of mutant control board is evaluated by making the following F examen: F= symbolize full-strength for between groupsmean square for with in groups =82.516.3 = 5.06 F proportions are interpreted by employ 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 lever of F needed for the significance at the 5 part transport is 3.55. Since our obtained F is greater than this, we reject the null possibil ity of no difference among these substance at the 5 percentage point. To summarize the above in a decision prototype 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 much(prenominal) a ratio, since such ratios are not large.

Test after the T test Since in the previous problem we found that there were strong differences between the means, the next task is to see where the difference or differences are. Winer (1921) summarized half-dozen differ ent methods for doing this. Some of these me! thods are more sloshed than the others and introduce 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.
