HandsOn 10  Coin Flipping
Now let's find out what is the real outcome of flipping a coin ten times. If you are using this site in a classroom setting, work in groups of two or three. Save time by "flipping'' ten coins at once: Shake up ten coins between your cupped hands and throw them on the table. Count the number of heads and report this number to the group member who is keeping record. Shake up the ten coins and drop them again. Again count the number of heads and report this number. Each group does this ten times.

Figure 3.1: Bar graph (a simple histogram) of number of students vs. number of heads to be completed when the "process'' of flipping coins is completed. Make your own scale (divisions) on the vertical axis.

Now combine the results for all the groups in the class. Have someone
make a graph like the one in Figure on the board. Place a large
X on the graph for the result of each trial, stacking the X's on
top of one another.
