Scrabble variants teams of 2, 3, or 4 race to play legal Scrabble words as quickly as possible. Scoring does not matter; all that matters is how quickly words are played. This can be a co-operative game where all players are simply trying to complete the game as fast as possible. A new variant on Scrabble introduced by Mattel on April 6, 2010. This game has the same rules and tiles as Scrabble, but the board is larger (21x21 vs. 15x15 in the original). With the larger board there are more premium squares, going up to quadruple letter and quadruple word scores.
P-value of this result is the chance of a fair coin landing on heads "at least" 14 times out of 20 flips. That probability can be computed from binomial coefficients as This probability is the "p"-value, considering only extreme results that favor heads. This is called a one-tailed test. However, the deviation can be in either direction, favoring either heads or tails. The two-tailed "p"-value, which considers deviations favoring either heads or tails, may instead be calculated. As the binomial distribution is symmetrical for a fair coin, the two-sided "p"-value is simply twice the above calculated single-sided "p"-value: the two-sided "p"-value
