Homework for Wednesday, March 20

Assignment:  Snake Eyes
Today we played Snake Eyes in class, the purpose of which was to collect data.  This was our experimental test of probability. 
Following the game, you should now have in your possession:
*Your data (as collected by your partner for you)
*Your partner's data (that you collected)
*Combined data totals (to reference as you complete this assignment.
You should also have a sheet(s) of graph paper which should illustrate the following:
*1 Title, then all labels and scales for 3 different graphs.
*Histogram of your data in one color
*Histogram of your partner's data in another color
*Histogram of the combined data with YOUR data in your color then your PARTNER'S data stacked on top of it. 
You now have 4 questions to answer as related to theoretical probabililty (what should happen):
First though: Yesterday I drew you the histogram for theoretical probability.  It represented all 36 possible rolls.  As I explained in class today, that graph is shaped like a perfect bell curve.  You will hear about bell curves a LOT, so remember that term! 
Check this out; it's a graph of possible dice rolls.  If you were to draw a curved line following the shape of the graph you would have a bell curve showing theoretically what should happen in 36 rolls.  See!?!?!


Anyway, as you answer the following questions, think less about the numbers and more about the shapes that you see in the graphs.  The primary reason we draw graphs in the first place is to be able to SEE data and to COMPARE it easily.  Talk about similiarities, differences, and anything you see in the graphs that you find interesting.  TALK to me and show me you understand what you see! 
Now for the questions -
1) Describe your graph as it compares to theoretical probability.
2) Describe your partner's graph as it compares to theoretical probability.
3) Describe the combined graph as it compares to theoretical probability.
4) Why do you think that experimental probability does not always produce statistics that math theoretical probability results?
