Maths: Decide My Flip Random Test

L.I: to create a test to tell whether WheelDecide.com is random or not.

This week for maths, our must do was to test whether WheelDecide.com is random or not. We had to do this with a pair, so I chose Alex. Our hypothesis was that we think that WheelDecide.com is random. The way we tested this was by one person flipping a plastic coin 100 times, and the other person spinning the Wheel Decide spinner 100 times, then switching roles. I started by flipping the coin, and Alex started by spinning the spinner. After we had spun and flipped 100 times, we ended up having the same results! 56 times landing on heads, and 44 times landing on tails. Then we switched roles, and the results ended pretty close. This time, it landed on heads 100 times, and tails 100 times for the coin flipping, and 94 heads and 106 tails for the Wheel. In the end, it seems that our hypothesis was indeed correct, because of the similarities of amount. We then as a class had to compare our results. In the end, we had flipped coins 2160 times, and had spun the wheel 2160 times. With our results, we had to create a Pie Chart to easily show it.


Hypothesis: We think the wheel decider is random.
Test: Comparing a random coin flip to the possibly random wheel decide.
