Well if we take Since we are ultimately concerned with the difference between two measures in one sample, the paired t-test reduces to the one sample t-test. (which can be found in the table using degrees of freedom and the pre-selected level of significance, α). If the absolute value of the calculated t-statistic is larger than the critical value of t

4/8/2016 · That’s kind of the idea behind degrees of freedom in statistics. Degrees of freedom are often broadly defined as the number of "observations" (pieces of information) in the data that are free to vary when estimating statistical parameters.

### The Paired Sample t-Test

Paired-sample t-test DePaul University. THis is the degrees. The paired sample t-test, sometimes called the dependent sample t-test, is a statistical procedure used to determine whether the mean difference between two sets of observations is zero. In a paired sample t-test, each subject or entity is measured twice, resulting in pairs of observations Open topic with navigation. The paired sample t-test is also called dependent sample t-test. It’s an univariate test that tests for a significant difference between 2 related variables. An example of this is if you where to collect the blood pressure for an individual before and after some treatment, condition, or time point..
