1. A p-value tells us the probability of obtaining an effect at least as large as the one we actually observed in the sample data. 2. An alpha level is the probability of incorrectly rejecting a true null hypothesis. 3. If the p-value of a hypothesis test is less than the alpha level, then we can reject the null hypothesis. 4. See more The alpha levelof a hypothesis test is the threshold we use to determine whether or not our p-value is low enough to reject the null hypothesis. It is often set at 0.05 … See more As mentioned earlier, the most common choice for the alpha level of a hypothesis test is 0.05. However, in some situations where there are serious … See more Here’s what we learned in this article: 1.
