Question

Let's say that a researcher conducts a study with 3 groups, each with 6 participants. Fill in the degrees of the following ANOVA table. freedom in df Source Between Within Total MS 34.43 6.95 F 4.95 D 17 Use the following Distributions tool to find the boundary for the critical region at a = .05 and - .01. To use the tool to find the critical F value, set both the numerator and the denominator degrees of freedom; this will show you the appropriate F distribution. Move the orange line ntil the area in the tail is equivalent to the alpha level you are investigating. F Distribution Numerator Degrees of Freedom - 26 Denominator Degrees of Freedom - 26 5000 .5000 .5000 1 5000 oo 0 2 1 1.000 At the a = .05 level of significance, the boundary of the critical region for this ANOVA IS: O 3.098 O 6.359 O 3.682 O 4.938

Answer 1

each with 6 participants Given I group of study and ie kas, n=18 1 source df Ims IF I Between 2 1 34.45 4.95 within is 6.95 Total Critical value at 2=005 = Foos. kt nok os, 2 , IS = 3.682 Coitical value at a=0:01 = Forol, klinck = fool,2,15 = 6-359 At a=0.05 Critical value < f ratio :. The null hypothesis can be rejected. At a = orol critical value nell hypothesis f ratio can not .. The be rejected.
