Let's say that a researcher conducts a study with 4 groups, each with 7 participants. Fill in the degrees of freedom in the following ANOVA table. Source Between Within Total df Use the following Distributions tool to find the boundary for the critical region at a = .05 and a = .01. 27 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.

Problem #7

To use the tool to find the F-ratio, set both the numerator and the denominator degrees of freedom; this will show you the appropriate F distribution. Move the orange line until the area in the tail is equivalent to the alpha level you are investigating. At the a = 0.05 level of significance, your conclusion is: o The null hypothesis can be rejected o The null hypothesis cannot be rejected
