The P-value provides a measure of this distance. The P-value (in this situation) is the probability to the right of our test statistic calculated using the null distribution. The further out the test statistic is in the tail, the smaller the P-value, and the stronger the evidence against the null hypothesis in …

Finding P-Values using the t-distribution Here is an example showing the three methods that you can use to find the P-Value when using the t-distribution. Example: Find the P-Value for a left-tailed test with n=27 and test statistic t = -1.500 Remember that the P-Value is the probability of getting a test statistic that is at least as

5. We will be using the P-value approach to hypothesis testing in this course, so we now have all the information we need to formally conduct our hypothesis test. Compare the P-value to your alpha level. If the P-value is less than or equal to alpha, you will reject the null hypothesis (H0) and conclude that the sample data support the alternative

Nonetheless, it is useful to have available a table of P-values for settings where computer access may not be available. Towards that end, this work provides a short set of tables for t- and 2-based P-values. P-VALUES Defined simply, a P-value is a data-based measure that helps indicate departure from a specified null hypothesis,

Calculation of P-Values Suppose we are doing a two–tailed test: • Null hypothesis: = 0 • Alternative hypothesis: ̸= 0 • Give the null hypothesis the beneﬁt of the doubt and assume that it is still the case that = 0. • Now calculate the P–value which is the smallest probability for which we would have rejected the null hypothesis.

Using Excel, Chapter 8: Hypothesis Testing - One Sample Excel alone does not conduct complete hypothesis tests1. However, once you calculate the test statistic, Excel can get the critical values and the P-values needed to complete the test. The functions used to get critical values and P-values are demonstrated here.

on your experiment the most important result is the p-value, highlighted at left in the pink cell. Since you set your alpha value at 0.05, if the p-value is less than 0.05, you can say that there is a statistically significant difference between the means of your two trials. Note that in this example, p = 2.6 x 10-16, which is < 0.05, so the
