F Test

Carlos Hilado Memorial State College Fortune Towne Campus F Test ( Sceffe Test) call By: Haironezza E. Abdullah MBA 201 The F Test We made an F outpouringing antecedently when raiseing he difference between deuce variables to attend to whether or not we should pool them. The analysis of chance variable control board is evaluated by making the following F test: F= destine consecutive for between groupsmean square for with in groups =82.516.3 = 5.06 F symmetrys are interpreted by design 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 nurture of F needed for the significance at the 5 pct diaphragm is 3.55. Since our obtained F is greater than this, we reject the null supp osition of no difference among these substance at the 5 percent point. To summarize the above in a decision put 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(prenominal) a ratio, since such ratios are not large.

Test after the T test Since in the previous problem we found that there were profound differences between the means, the next task is to see where the difference or differences are. Winer (1921) summarized half-dozen different m ethods for doing this. Some of these methods! are more harsh than the others and diddle 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.
