Witryna21 lis 2024 · In our example, the p-value is 0.02, which is less than the pre-specified alpha of 0.05, so the researcher concludes there is statistical significance for the study. What does this mean? The p-value assumes the null hypothesis is true and provides the probability of results in excess as the ones observed IF the null hypothesis is true. The notion of a zero-probability event plays a special role in probability theory and statistics because it underpins the important concepts of almost sure property and almost sure event. Often, we want to prove that some property is almost always satisfied, or something happens almost always. "Almost … Zobacz więcej As we said, the definition is very simple. Despite the simplicity of the definition, there are some features of zero-probability events that might seem paradoxical.

WitrynaThe null is not rejected unless the hypothesis test shows otherwise.

The three hypotheses can be rewritten by stating how p1 - p2 is related to the value zero. To be more specific, the null hypothesis would become H 0: p1 - p2 = 0. The potential alternative hypotheses would be written as: breaking bad season 3 episode 13 recap
