Question: Assume that we recruited a different sample of five dogs and attempted to replicate the Quaranta and colleagues (2007) study described in Exercise. The source table for our fictional replication appears below. Find the critical F value and make a decision regarding the null hypothesis. Based on this decision, is it appropriate to conduct post-hoc comparisons? Why or why not?
Exercise: How does a dog's tail wag in response to seeing different people and other pets? Quaranta, Siniscalchi, and Vallortigara (2007) investigated the amplitude and direction of a dog's tail wagging in response to seeing its owner, an unfamiliar cat, and an unfamiliar dog. The fictional data below are measures of amplitude. These data reproduce the pattern of results in the study, averaging left tail wags and right tail wags. Use these data to construct the source table for a one-way withingroups ANOVA.
