Webb1 juli 2024 · In your example, T1 and T12 are highly correlated with almost every variable then, those independent variables are susceptible to cause the multicollinearity problem. This fact is also captured in the p-value. Multicollinearity implies lower confidence in the p-value test but lower confidence in the p-value test does not imply multicollinearity. Webb12 mars 2024 · 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.

WebbMisinterpretation #3: A p-value of 0.001 means that the effect is stronger than with a p-value of 0.03. A p-value says nothing about the size of the effect. One important thing to note is that p-values are sensitive of the size of the sample you are working with — all other things held constant, a larger study will yield lower p-values. Webb18 maj 2024 · Typically, before we conduct a hypothesis test, we choose a threshold value. If we have any p-value that is less than or equal to this threshold, then we reject the null hypothesis. Otherwise we fail to reject the null hypothesis. This threshold is called the level of significance of our hypothesis test, and is denoted by the Greek letter alpha.
