Hypothesis tests are crucial when you want to use sample data to make conclusions about a population because these tests account for sample error. Using significance levels and P values to determine when to reject the null hypothesis improves the probability that you will draw the correct conclusi...

19 Ss (faculty and graduate students) were asked to indicate degree of belief in research results at different p values, once with an n of 10 and then with n equal to 100. Ss had greater confidence in the p levels when they were associated with the larger sample size. Graduate students...
Use significance levels during hypothesis testing to help you determine which hypothesis the data support. Compare yourp-valueto your significance level. If the p-value is less than your significance level, you can reject the null hypothesis and conclude that the effect is statistically significant....

P-values are important as they provide a universal language to the test results. As different researchers use different levels of significance while testing a hypothesis, it might be difficult to compare the result from two tests. In such cases, p-values can be determined and used to interpret...
