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 heads and is a two-tailed test. Suppose the researcher observes heads for each flip, yielding a test statistic of "n" and a "p"-value of 2/2. If the coin was flipped only 5 times, the "p"-value would be 2/32 = 0.0625, which is not significant at the 0.05 level. But if the coin was flipped 10 times, the "p"-value would be 2/1024 ≈ 0.002, which is significant at the 0.05 level. In both cases the data suggest that the null hypothesis is false (that is, the coin is not fair somehow), but changing the sample size changes the "p"-value. In
