1. A dog groomer is often asked if small dogs bark more than larger dogs. To test this, he logs the number of separate barking episodes per day for three size dogs: small, medium, and large. Below is the number of barking episodes for 36 dogs. What are the independent and dependent variables in this study? On average, which size dog barked the most? Report the mean. On average, which size dog barked the least? Report the mean. Do the different size dogs bark a significantly different number of times? Test with an α = 0.05. If appropriate, use Tukey’s HSD post hoc test and report where the differences are. If inappropriate, state why. Calculate and interpret the effect size.
