The p-value (denoted p) for a set of data is the probability that the given data (or something even more unusual) would occur if the hypothesis being tested is not true. How do you find p-value from z-statistic? To calculate the p-value, first find the test statistic, a value that...
So you need to find the p-value for your hypothesis test. To do so, employ the spreadsheet program Microsoft Excel. Using a simple formula, you can easily determine the p-value for your tests and thereby conclude strong or weak support of the null hypothesis....
Related to this Question Find the approximate p-value for the test and interpret its value. Determine the p-value for this test. Determine the P-value for this hypothesis test. Suppose you conduct a test and your p-value is equal to 0.002. What can you conclude?
Find the p-value with the T-TEST function One-tailed p-value Two-tailed p-value What is a p-value? P-Value is used to perform hypothesis testing. It indicates how statistically significant a value might be. The p-value tells if a null hypothesis is valid or not. It can be measur...

A P value is a measure of strength-of-evidence -- of how well (or how poorly) your data comply with the null hypothesis. A statement of 'significance' is a way to divide all your tests into two piles -- ones that you think are worthy of follow up ('signif...
For example, to be statistically significant at the 0.01 significance level requires more substantial evidence than the 0.05 significance level. However, there is a tradeoff in hypothesis tests. Lower significance levels also reduce the power of a hypothesis test to detect a difference that does ...
The “p-value” represents the chance that the statistical summary would be equal to or greater than the observed value when the null hypothesis is valid for a particular statistical model. Though the “p-value” often gets expressed as a decimal number, it is generally better to describe it...
We will calculate the p-value to determine if we should accept or reject the null hypothesis. Consider the following data: Solution: Step 1:Selectcell B9and write the below formula: =T.TEST(A2:A7,B2:B7,1,2) Step 2:Press “Enter,” and Excel will calculate the p-value as0.38692incell...
The p-value approach to hypothesis testing uses the calculated probability to determine whether there is evidence to reject the null hypothesis. This determination relies heavily on the test statistic, which summarizes the information from the sample relevant to the hypothesis being tested. The null h...
