Option 2:

Flip a coin 10 times and record the observed number of heads and tails. For example, with 10 flips one might get 6 heads and 4 tails. Now, flip the coin another 20 times (so 30 times in total) and again, record the observed number of heads and tails. Finally, flip the coin another 70 times (so 100 times in total) and record your results again.

We would expect that the distribution of heads and tails to be 50/50. How far away from 50/50 are you for each of your three samples? Reflect upon why might this happen?

MY RESULTS:

Sample 1 - Heads: 5 , Tails: 5 (50/50)

Sample 2 - Heads: 9 , Tails: 11 (45/55)

Sample 3 - Heads: 43 , Tails: 27 (61/39)
