Statistische T-Distribution - Die & # 147-T-Table & # 148-
Als statistisches Werkzeug, listet ein T-Tabelle kritische Werte für zweiseitige Tests. Sie verwenden diese Werte dann Vertrauenswerte zu bestimmen. Die folgende Tabelle zeigt t-Freiheitsgrade für ausgewählte Perzentile von der 90. bis zur 99.:
Freiheitsgrade | 90. Perzentile (a = 0,10) | 95-Perzentil (a = .05) | 97,5 Perzentile (a = .025) | 98. Perzentile (a = .02) | 99. Perzentile (a = .01) |
