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.

With the larger board there are more premium squares, going up to quadruple letter and quadruple word scores.
P-value formula_16 (left-tail event) or the "smaller" of formula_17 and formula_15 (double-tailed event). Thus, the "p"-value is given by The smaller the "p"-value, the higher the significance because it tells the investigator that the hypothesis under consideration may not adequately explain the observation. The null hypothesis formula_4 is rejected if any of these probabilities is less than or equal to a small, fixed but arbitrarily pre-defined threshold value formula_23, which is referred to as the level of significance. Unlike the "p"-value, the formula_23 level is not derived from any observational data and does not depend on the underlying hypothesis; the value
