When we want to compare the means of two data groups, we often use a difference test. The most commonly used difference test is the t-test. In a t-test, the samples being compared can be either paired or independent.
Differential testing is aimed at determining the mean differences in the tested sample groups. In practice, paired sample t-test, independent sample t-test, and one-way ANOVA are often used to test means in more than one sample group.
The t-test is commonly used to test the mean difference between two samples. The t-test can be performed on paired samples as well as independent samples. When should we use the paired sample t-test and when should we use the independent sample t-test?
Excel can be used for several data analyzes, including t-tests. Researchers can use the t-test to test the difference in the mean of two variables. The t-test that researchers often use can be divided into two: the paired sample t-test and the independent sample t-test. Because researchers often use the two t-tests, I will discuss …
