We set the 3rd argument of the function to2as we are doing a two-tailed t-test on the dataset. The 4th argument should be2for a two-sample equal variance t-test. Case 1.2 – Paired T-Test We are going to apply another formula to calculate thePaired T-Test. The following dataset sh...
This article describes how to do apaired t-test in R(or inRstudio). Note that the paired t-test is also referred asdependent t-test,related samples t-test,matched pairs t testorpaired sample t test. You will learn how to: Perform the paired t-test in Rusing the fo...
There is only one dependent t-test, known as thepaired t-test. However, there are two independent t-tests: the equal variance and the unequal variance t-tests. We discuss how to perform each of these tests in the next section. But before you learn how to do them, it is imperative th...

=T.TEST (B1:B8, C1:C8, 1 It refers to the number of distribution tails. We have set it to 1 because we are finding a one-tailed p-value. 4. The t-test type argument can be set to three modes. 1 = paired. 2 = two-sample equalvariance(homoscedastic) ...

You can compute percentages in Excel in a variety of ways. Excel may be used to determine the % of right answers on a test, discount prices using various percent assumptions, and calculate the percent change between two numbers, for example. In Excel, calculating a percentage ...

Thet-test is one of the most basic statistical tests, and it's easy to compute in Excel with the Toolpak. Click theData Analysisbutton and scroll down until you see thet-test options. You have three choices: t-Test: Paired Two Sample for Meansshould be used when your measurements or ...
The result using the NPV function for the example comes to $722,169. Then subtract the initial outlay from the value obtained by the NPV function to compute the final NPV. NPV = $722,169 - $250,000 or $472,169. This computed value matches that obtained using the first method. ...
