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 5 and a "p"-value of formula_34, which is exactly what is expected. Suppose instead that the test statistic for this experiment was the "number of alternations" (that is, the number of times when H followed T or T followed H), which is one-tailed. That would yield a test statistic of 9, which is extreme and has a "p"-value of formula_35. That would be considered extremely significant, well beyond the 0.05 level. These data indicate that, in terms of one test statistic, the data set is extremely unlikely to have occurred by chance, but it does not suggest that the coin
