1. Labrador Retriever - Average weight: 55-80 pounds
2. German Shepherd - Average weight: 50-90 pounds
3. Golden Retriever - Average weight: 55-75 pounds
4. Bulldog - Average weight: 40-50 pounds
5. Beagle - Average weight: 20-30 pounds
6. Poodle - Average weight: 45-70 pounds
7. Boxer - Average weight: 50-80 pounds
8. Dachshund - Average weight: 11-32 pounds
9. Chihuahua - Average weight: 2-6 pounds
Mean: (80 + 90 + 75 + 50 + 30 + 70 + 80 + 32 + 6) / 9 = 52.11 pounds
Median: In ascending order - 30, 32, 40, 45, 50, 55, 70, 75, 80, 80, 90. Median = 55 pounds
Mode: 80 pounds
In this case, the mean would be the best measure of central tendency as it takes into account all the weights of the different breeds and provides an average that reflects the overall distribution of data. The median may be slightly skewed in this case due to certain breeds with higher weights, while the mode may not be as representative of the overall data set.
