When using T-Scores, the mean (average) is always 50, and the standard deviation is 10. If your T-Score is above 50, then it is above average. If your score is less than 50, it is below average. For example, if you have a T-Score of 60, you scored higher than 84% of all organizations.T-Scores are distributed in a bell-shaped curve, as illustrated in the diagram to the right. 68% of T-Scores fall between 40 and 60. 96% of scores fall between 30 and 70.f your score is less than 50, it is below average. For example, if you have a T-Score of 60, you scored higher than 84% of all organizations. T-Scores are distributed in a bell-shaped curve, as illustrated in the diagram to the right.
A tetrarch is one of a group of four rulers who share rule over a kingdom or Empire.
In mathematics, tetration (or hyper-4) is the next hyperoperator after exponentiation, and is defined as iterated exponentiation. The word was coined by Reuben Louis Goodstein, from tetra- (four) and iteration. Tetration is used for the notation of very large numbers. Shown here are examples of the first four hyperoperators, with tetration as the fourth (and succession, the unary operation denoted taking and yielding the number after, as the 0th): 1  Addition.
