1-sample T Test Degrees Of Freedom. In this lesson you will learn the difference between statistical verses’ practical significance (which evaluates whether the observed difference is large enough to have a practical impact on the process).
You will grasp why degrees of freedom are often broadly defined as the maximum number of "observations" (pieces of information) in the data that are free to vary when estimating statistical parameters.
You will understand the 1-SAMPLE T-TEST which is a parametric test, and how to calculate it from a range of data values and use an example to show its application.
