FlipSite: 5, 6 years of Coin Flip Simulations.It
is also able to hit the summary data, e.g. the total of heads and tails
up to that point, and generate a running total, so it can let me know
that there have been 3,341,614 total flips, where 1,669,175 have been heads and 1,672,439 have been tails.
But watching coin flips does not teach much, that is just the
teaser. What John dreamed up and we built were other tools, including:
- Flip Parade: allows you to see a graphic
display of series of flip results for any point in time between January
1 and the current date and time..
- Flip Streaks:
allows you to query how many times, say a streak of 12 heads has
occurred in the history of the year. From the results, students can
repeat this streak on the Flip Parade, and then they can visually test
their assumptions about what follows (some assume there might be a long
set of tails, but probability states.... well, you should fill it in).
- Experiments:
using the flip data, you can set up tests to find frequency
distributions of coin flips for X number of people each flipping a coin
Y times (you enter the X and Y for your own experiments). The site
generates a frequency distribution and then students are encouraged to
compare the results to the mathematical prediction.
But it is cool to see that old technology and good ideas can still cook together. Go play:
