Question

Pet preference was compared for four different types of animals (dogs, cats, birds, and fish), using a one-way within-groups ANOVA with seven participants. The standard error was calculated as 0.21. Given the following means for preference:

Dogs M = 4.43, Cats M = 4.18, Birds M = 2.73, Fish M = 4.07

1. where are the significant effects for preference among these groups?

A -Birds and fish are less preferred than dogs and cats, but there are no other differences present.

B -Preference for birds is significantly lower than for the other three groups, and there are no other differences among the mean preferences.

C - All post-hoc tests were significant at the 0.05 level.

D - Dogs and cats are preferred over birds and fish, but there are no differences between the other groups.

What are the critical cutoffs for the two-tailed Tukey HSD tests for these data, assuming a p level of 0.05?

A - 4.0

B - 3.96

C - –4.0 and 4.0

D - –3.96 and 3.96

what is the Tukey HSD value when comparing data for dogs and cats?

A - 0.544

B - 0.198

C - 1.714

D - 1.190

A -Birds and fish are less preferred than dogs and cats, but there are no other differences present.

C - All post-hoc tests were significant at the 0.05 level.

D - Dogs and cats are preferred over birds and fish, but there are no differences between the other groups.
