The Acme Veterinary Nutrition Laboratory wants to find out if its three dog foods appeal to all dogs equally or if breed is a factor in a dog’s food preference. Per the research criteria specified, you recruit 90 pets: 30 Cocker Spaniels, 30 Beagles, and 30 Keeshonds. Owners are asked not to feed their pets for 4 hours prior to the test. Each dog is tested individually; the dog is placed 5 feet (1.5 meters) away from three clear bowls of dog food, all with equal weights. On cue, the leash is removed and the dog is free to eat from any bowl(s). After dismissing each participant, you weigh the bowls; the lightest bowl wins (meaning that the dog ate the most food from that bowl). In case of a tie, the winning bowl is the one that the dog went to first.
Data set: Ch 09 - Exercise 08A.sav Codebook Variable: dog Definition: Dog breed Type: Categorical (1 = Cocker Spaniel, 2 = Beagle, 3 = Keeshond) Variable: food Definition: Dog food preference (the lightest bowl by weight) Type: Categorical (1 = Food A, 2 = Food B, 3 = Food C)
1. Write the hypotheses.
2. Run the criteria of the pretest checklist (n is at least 5 per cell in the crosstabs) and discuss your findings.
3. Run the chi-square test and document your findings (ns and/or percentages, Sig. [p value]).
4. Write an abstract up to 200 words detailing a summary of the study, the chi-square test results, hypothesis resolution, and implications of your findings.
