Coin Toss Not Completely Random

Researchers at the University of British Columbia (UBC) have conducted a study to determine whether or not the toss of a coin results in a completely random outcome, 50% heads or tails. The study involved 13 students who where observed tossing a coin 300 times each and recording of the results of each toss. Prior to starting each participant was given some instruction on coin toss technique and time to practice. The results showed that on average heads came up 57% of the time with one participant achieving a whopping 68%.

I know a few curlers who'd love to get there hands on those instructions! In fact I've heard that former Canadian Champion Colleen Jones was known to have practiced the toss of a coin hundreds of times trying to gain an edge, if ever so slightly. Perhaps she was onto something?

Btw, there was no mention of the denomination of the coins or whether or not the same coin, or same series (year) of coin was used.
