you will learn how to Calculate P Value in Excel. The p-value, short for probability value, is an important concept in statistical hypothesis testing. Its used in hypothesis testing to quantify the idea of statistical significance of evidence. By running T-Test in excel, we can actually arrive at the statement whether the null hypothesis is TRUE or FALSE. Look at the below example to understand the concept practically. Well be working on a hypothetical weigh loss process. First thing we need to do is calculate the difference between before diet and after diet. Once we have the formula applied for every cell, go to Data tab and under it click on Data Analysis. Find T. Test: Paired Two Sample for Means. Select variable range 1 and variable range 2. Leave alpha value at 0. 05. Now select the Output Range, i. e, where you want to display your analysis results. Click OK. Now lets select the results cells for One Tail and Two Tail and click the percentage under Home tab. Add decimals if needed. On the results, we can see that the p-value with the one-tail test is 0. 64% and the p-value with the two-tail test is 1. 28%. Both results show that the p-value is lower than 5%, which means the null hypothesis is significant. This may seem confusing at once but should be straightforward once you familiarize yourself with Excel. What other excel tutorials would you like us to make?

the data sets I am comparing have different data sets within them e. g. one set has 10 values, the other has 15 values and another having 22, how can I compare this data to find the p-value, as one way anova requires you to have the same number of data in each set

if the p-value is lower than 5%, the null hypotheses is rejected and NOT the null hypothesis is significant. Stop teaching it wrong! where did you learn this?

Ok my question is how exactly would you format a null hypothesis for this? I understand that the p-value shows a significance but a significance for what?

Can you explain what this data table is about and what we are actually trying to figure out by this analysis here?
