   • What were the similarities in the tools and strategies used to organize and summarize the data?
     
     
   • What were the differences in the tools and strategies used to organize and summarize the data?
     
     
   • Now that you have seen another group’s approach, is there anything you would adapt or include in your strategy for organizing and summarizing the data?
     
     
   • Did you reach the same conclusion as the other group? If not, what were the main differences?
