Lösung
Bin selber drauf gekommen:
Berechnung von T-Scores
T Scores (M = 50, S = 10)
T= 50 + (10*(Xi - M))
-----------------------
S
Xi = Individual Raw Score
M = Grand Mean
S = Standard Deviation
or simply:
T = (z)(10) + 50
T Score expresses distance from the mean in standard deviation units, with normality it is also associated with a particular percentile
T = 50
Score is exactly on the mean
T = 60
Score is 1 SD above the mean
