8. FAIR COIN TeamCroatia Reviewer: Luka Mik i
PROBLEM TEXT In many cases, disputes are resolved with a coin toss. It is presumed that this procedure gives equal chances of winning to both sides. Investigate how the chances depend on the tossing mechanism and the coin properties. 2
REPORTER Covered statistics Important coin properties No statistics to test if the coin is fair (chi squared test) Coin material and hole tested, but not a coin with a bulge Analysis of problem Analysis of data Theoretical introduction Hypotheses Experiment Conslusion OK Not so good Very good 3
OPPONENT Good question about the position of the hole Noticed the lack of prooving randomness Said almost no parameters enough parameters were tested Comparison of different surfaces interesting point 4
DISCUSSION Displacement of barycenter? Does the material of the coin influence the results? Already tested in the presentation What about physical forces? Wasn t really discussed What if the coin is made of one material and covered with another? Didn t discuss the other parameters (air currents) 5
