S.3.2 Hypothesis Testing (P-Value Approach) STAT ONLINE

WebThe p-value of the t-test depends on the direction of the alternative hypothesis. p-Value of t test If the test statistic t has t distribution with n − 1 degrees of freedom, then the p -value of the test for testing a. left-tailed hypothesis is p -value = P ( t n − 1 ≤ t). b. right-tailed hypothesis is p -value = P ( t n − 1 ≥ t). One thing to note, a high p-value does not prove that your groups are equal or that there is no effect. High p-values indicate that your evidence is not strong enough to suggest an effect exists in the population. An effect might exist but it’s possible that the effect size is too small, the sample size is too small, or there … See more I’ve written about hypothesis testing and interpreting p-values in many other blog posts.

WebApr 18, 2024 · Here is the technical definition of P values: P values are the probability of observing a sample statistic that is at least as extreme as your sample statistic when you assume that the null hypothesis is true. Let’s go back to our hypothetical medication study. Suppose the hypothesis test generates a P value of 0.03. WebJan 22, 2024 · This means that the p-value for a one-sided test is between 0.1 and 0.05. Let’s call it .075. Since our t-test is two-sided, we need to multiply this value by 2.

The high p-value(>5%) tells us that there is not enough evidence to reject the null hypothesis. Alternatively, we can say that the evidence is not enough to prove that the group means are different. The 95% confidence interval is also shown.

Step 2: Find the test statistic. Step 3: Find the p-value for the test statistic. To find the p-value by hand, we need to use the t-Distribution table with n-1 degrees of freedom. ...

WebConsequently, the F-test has a low p-value (it is saying that the predictors together are highly significant in explaining the variation in the response variable). But the t-test for each predictor has a high p-value because after allowing for the effect of the other predictor there is not much left to explain.
