WebFeb 13, 2024 · To determine the p-value, you need to know the distribution of your test statistic under the assumption that the null hypothesis is true.Then, with the help of the cumulative distribution function (cdf) of this distribution, we can express the probability of the test statistics being at least as extreme as its value x for the sample:Left-tailed test: p … WebFeb 28, 2014 · A p-value is not a probability that the null hypothesis is true. For example, if you took a thousand cases where the null hypothesis is true, half of them will have p < .5. Those half will all be null. Indeed, the idea that p > .95 means that the null hypothesis is "probably true" is equally misleading.

In simpler words, it is used to reject or support the null hypothesis during hypothesis testing. In data science, it gives valuable insights on the statistical significance of an independent variable in predicting the dependent variable.

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. So, our estimated p-value is .075 * 2 = 0.15. Step 4: Draw a conclusion. Since this p-value is not less than our chosen alpha level of .05, we can’t reject the null hypothesis ...
