In this post, I provide step-by-step instructions for using Excel to perform t-tests. Importantly, I also show you how to select the correct form of t-test, choose the right options, and interpret the results. I also include links to additional resources I’ve written, which present clea...
When it comes to hypothesis testing, calculating P-values is an essential step to determine the significance of your results. In Excel, there are several ways to calculate P-values, including using built-in formulas such as TDIST and TTEST. However, another powerful tool to help you w...
how we can establish t-test calculation in MS Excel. What is a t-test? A t-test/ Student t-test is a statistical tool to determine the degree of significant difference between the means of two population groups. The groups may be related to certain features. This hypothesis testing tool ...
Large p-values might lead you to act like the null hypothesis is true, even though you know that it’s not really true, just a reasonable model. To learn more, check out this glossary of Lean Six Sigma terms Let’s work through a practical example in Excel. We’ll begin with one-...
*This process is made much easier if you use a TI-83 or Excel to calculate the z-score (the “critical value”). See: Critical z value TI 83 Z Score in Excel Hypothesis Testing Examples: Mean (Using TI 83) You can use theTI 83calculator for hypothesis testing, but the calculator wo...

Calculating the “p-value” of a model and proving/disproving the null hypothesis is surprisingly simple with MS Excel. There are two ways to do it. Let’s dig in. Null Hypothesis andp-Value The null hypothesis is a statement, also referred to as a default position, claiming that the re...
The sum of all the Chi-Square P values should be 1 if the null hypothesis is true. We reject the null hypothesis if the test statistic is too large in the present dataset. As the above example shows, calculating Chi-Square and testing for the significance of hypothesized data in statistics...
You will see it being used for statistical hypothesis testing everywhere around you. Whether you are a statistician, an engineer, an accountant, or a scientist – you’ll have to use p-value for a variety of jobs.There are two easy ways to calculate p-value in Excel. ...
This beginner-friendly guide will equip you with the knowledge to confidently find p-values in Excel. We'll break down what p-value means, and explore some of the common places where a p-value shows up, such as the in output of common functions used in hypothesis testing, such as t-te...
