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...

One-sample t-test: Used to test the claim about one population where one sample was observed. Independent t-test: Used to compare the means of two different populations. Paired t-test: Used to compare the means of two samples from ...
The independent, or unpaired, t-test is a statistical measure of the difference between the means of two independent and identically distributed samples. For example, you may want to test to determine if there is a difference between the cholesterol leve
In this post, you’ll learn about the different types of t tests, when you should use each one, and their assumptions. Additionally, I interpret an example of each type. Which T Test Should I Use? To choose the correct t test, you must know whether you are assessing one or two group...
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...
You will learn how to: Perform the independent t-test in R using the following functions : t_test() [rstatix package]: the result is a data frame for easy plotting using the ggpubr package. t.test() [stats package]: R base function. Interpret and report the two...
What is a paired titer? Serologic testing is used for organisms that are difficult to culture (such as viruses); an answerk may be obtained in hours to days. The samples can be "paired sera" with an initial "acute" titer followed by a "convalescent" titer in about 2 weeks to determine...
The terms “two-way” and “three-way” refer to the number of factors or the number of levels in your test. Four-way ANOVA and above are rarely used because the results of the test are complex and difficult to interpret.A two-way ANOVA has two factors (independent variables) and one...
