tTestwert

P ( t ) Repräsentiert die ansteigende Fraktion der Standard Normalverteilung, geringer als der Wert t

R ( t ) Repräsentiert die ansteigende Fraktion der Standard Normalverteilung zwischen dem Wert t und 0. R ( t ) =1 – ( t )

Q ( t ) Repräsentiert die ansteigende Fraktion der Standard Normalverteilung größer als der Wert t Q ( t ) = 0.5 – ( t )
