  1. Organize these data in a way that would help you find which kind of bear is heavier — grizzly bears or black bears. (You can use another piece of paper to do this. Please be sure to put your name on it!)

  2. Write down three things that you can tell about the weights of the bears. (You may want to use your answer from question 1 to help you.)
