See what you know about the degrees of freedom. Utilize interactive quiz questions to test your skills, in addition to a printable worksheet. These...... The 1-sample t-test estimates only one parameter: the population mean. The sample size of n constitutes n pieces of information for estimating the population mean and its variability. One degree of freedom is spent estimating the mean, and the remaining n-1 degrees of freedom estimate variability. Therefore, a 1-sample t-test uses a t-distribution with n-1 degrees of freedom

### Open topic with navigation. Paired t Test Menu location: Analysis_Parametric_Paired t. This function gives a paired Student ttest, confidence intervals for the difference between a pair of means and, optionally, limits of agreement for a pair of samples (Armitage and Berry, 1994; Altman, 1991).

- The significance test is conducted by computing Chi Square as follows. The degrees of freedom is equal to (r-1)(c-1), where r is the number of rows and c is the number of columns. For this example, the degrees of freedom is (2-1)(4-1) = 3.
- If sphericity assumption is viloated (you get a significant Chi-Squared value in the Sphericity test or the Huynh-Feldt Epsilon is lower than 1 you should correct the degrees of freedom for the F
