The dependent t-test (also called the paired t-test or paired-samples t-test) compares the means of two related groups to determine whether there is a statistically significant difference between these means.

Paired t tests are also known as a paired sample t-test or a dependent samples t test. These names reflect the fact that the two samples are paired or dependent because they contain the same subjects.
21 paź 2024 · The dependent samples t-test is used when you want to test whether two means from one group measured at two different times are significantly different. This is sometimes referred to as a paired samples t- test or a repeated measures t -test.
21 paź 2024 · The dependent samples t-test formula is as follows: \[t=\dfrac{\Sigma d}{\sqrt{\left[\dfrac{n\left(\Sigma d^2\right)-(\Sigma d)^2}{n-1}\right]}} \nonumber \] The two symbols are \(n\) which stands for sample size, and \(d\) which stands for difference from pretest to posttest. Difference (\(d\)) is calculated by subtracting each pretest score ...
Understanding the hypothesis of the dependent t-test, how to use the test for different subjects (matched-pairs designs), correctly reporting the output and whether to include confidence intervals in the results.
The dependent samples T-test, or also known as the dependent t-test, tests whether the mean values of two dependent groups differ significantly from each other. Why do you need the dependent t-Test? You need the paired t-test whenever you survey the same group or sample at two points in time.
A dependent t-test, also known as a paired samples t-test, is a statistical method used to compare the means of two related groups. This test is particularly useful when the same subjects are measured before and after a treatment or intervention, allowing researchers to determine if there is a significant difference in their responses.
