Question

QUESTION 1 After a one-way ANOVA test, you conduct all possible post-hoc pairwise comparisons using the Bonferroni correction. If there were 4 groups (J = 4), what would your adjusted alpha value be for the post-hoc tests? Remember, our alpha is 0.05 for the class. Round final answers to four decimal places. QUESTION 2 After a one-way ANOVA test, you conduct all possible post-hoc pairwise comparisons using the Bonferroni correction. If there were 6 groups (J = 6), what would your adjusted alpha value be for the post-hoc tests? Remember, our alpha is 0.05 for the class. Round final answers to four decimal places. QUESTION 3 Use the partial one-way ANOVA table below to find the missing values: SS Source Between Within Total 168 What is the df within? Round all final answers to two decimal places, all intermediary work to four.

Answer 1

1) total number of pair =(₄C₂) =6

therefore adjusted alpha value =0.05/6 =0.0083 ( please try 0.0085 if this comes incorrect due to rounding)

2)

total number of pair =(₆C₂) =15

therefore adjusted alpha value =0.05/15 =0.0033 ( please try 0.0034 if this comes incorrect due to rounding)

3)

df within =dftotal-dfbetween =19-5 =14
