Make Your Predictions

The staff at the shelter know there is a relationship between how much an animal weighs and how much it eats. They’re about to order food for the month, and need some help analyzing the distribution of animals' weights!

1 Imagine a typical animal from each of these four species. Rank the animals from lightest (1) to heaviest (4).
dog: rabbit: cat: tarantula:

2 Circle the species you expect to have the greatest variability in weight: dog rabbit cat tarantula

3 Circle the species you expect to have the least variability in weight: dog rabbit cat tarantula

4 The dot plots below display the weight distributions of dogs, rabbits, and tarantulas. Identify the species of each plot.

Test Your Predictions Using Pyret

6 Using the Dogs, Rabbits, Cats & Tarantulas Starter File, build a dot plot for each species. In your code, use the tables defined on lines 22-25. Use information from your dot plots to fill in the cells. You can hover your mouse over specific points on the dot plot for additional information on an individual animal. Some cells have been completed for you.

7 Purchasing dog food would be easier if every dog ate roughly the same amount of food! But is that true for dogs? What about rabbits, or any of the four species in the Dogs, Rabbits, Cats & Tarantulas Starter File? Can you make any recommendations about quantity of food to purchase?
