Basic Statistics: Difference between P-Value and Alpha?
WebIn the majority of analyses, an alpha of 0.05 is used as the cutoff for significance. If the p-value is less than 0.05, we reject the null hypothesis that there's no difference between the means and conclude that a significant difference does exist. If the p-value is larger than 0.05, we cannot conclude that a significant difference exists. Bei einem statistischen Test wird eine Vermutung (Nullhypothese) überprüft, indem ein passendes Zufallsexperiment durchgeführt wird, das die Zufallsgrößen liefert. Diese Zufallsgrößen werden zu einer einzelnen Zahl, Prüfgröße genannt, zusammengefasst: Für einen konkreten Versuchsausgang des Experiments erhält man einen Wert WebAn alpha value is the proportion of repeated trials you’re willing to accept as incorrectly rejecting your null hypothesis. For example, i’d your alpha = 0.05, that means you are willing to incorrectly reject your null 1 times out of every 20.
