The "two-way" comes because each item is classified in two ways, as opposed to one way.

The two-way ANOVA that we're going to discuss requires a balanced design.

Athlete type included three levels (football, basketball, soccer players) and age consisted of two levels (younger, older). The balanced design is where each treatment has the same sample size. For an interaction between factors, the degrees of freedom is the product of the degrees of freedom for the corresponding main effects. We now head to the F-table and look up our critical values using alpha = 0.05.

The population means of the first factor are equal. byKen Plummer 5494views Reporting a one-way anova byKen Plummer 26345views Reporting a one way repeated measur... All effects were statistically significant at the .05 significance level except for the Age factor. The p-value for the Race factor is the area to the right F = 13.71 using 1 numerator and 24 denominator df.

It reflects my current understanding of degrees of freedom, based on what I read in textbooks and scattered sources on the web. The main effect for age yielded an F ratio of F(1, 63) = 2.9, p > .05, indicating that the effect for age was not significant, younger (M = 5.97, SD byKen Plummer 17787views Reporting a single linear regressio... If there were 2 replications at each combination of the 2 factors, you would have s2 on 2-1 degrees of freedom at each combination.

The main effect for athlete type yielded an F ratio of F(2, 63) = 136.2, p < .001, indicating a significant difference between football players (M = 9.39, SD = 1.99), Reporting the Study using APA • You can report that you conducted a Factorial ANOVA by using the template below. • “A Factorial ANOVA was conducted to compare the main effects The main effect for athlete type yielded an F ratio of F(2, 63) = 136.2, p < .001, indicating a significant difference between football players (M = 9.39, SD = 1.99), Athlete type included three levels (football, basketball, soccer players) and age consisted of two levels (younger, older).

The p-value for the Race factor is the area to the right F = 17.58 using 2 numerator and 24 denominator df. An experimental design is said to be balanced if each combination of factor levels is replicated the same number of times. The numerator df is the df for the source and the denominator df is the df for the error. The type of seed and type of fertilizer are the two factors we're considering in this example.

In this case, 2 samples from each treatment group were taken. Reporting Results using APA • A two-way analysis of variance was conducted on the influence of two independent variables (athlete type, age) on the number of slices of pizza eaten in I couldn’t find any resource on the web that explains calculating degrees of freedom in a simple and clear manner and believe this page will fill that void. The main effect for age yielded an F ratio of F(1, 63) = 2.9, p > .05, indicating that the effect for age was not significant, younger (M = 5.97, SD

The interaction effect was significant, F(2, 63) = 13.36, p < .001. 15.

F = 13.71 is for the gender source, so it would be used to determine if there is a difference in the mean reaction times of the different genders.

The factors are called the "row factor" and the "column factor" because the data is usually arranged into table format.
