Question

A repeated-measures study using a sample of n = 20 participants would produce a t statistic with df = ____.​

BlackTom AI · Accepted Answer

The question asks about the degrees of freedom (df) for a repeated-measures study with n = 20 participants.
In a repeated-measures (paired) t-test, each participant contributes a pair of related observations, and the analysis is performed on the within-subject differences.
For this setup, the df are calculated from the number of subjects minus one, i.e., df = n − 1.
With n = 20, df = 20 − 1 = 19.
It’s also worth noting that the provided answer list is empty in this case, so there are no explicit options to assess here. Generally, for a between-subjects (independent groups) t-test, df would be n1 + n2 − 2, but that formula does not apply to a repeated-measures design.

The degrees of freedom of a 4 x 5 table is:

What happens as the df of a dataset is increased?

A researcher reports df = 18 for a repeated-measures t statistic. This research study used a total of n = 19 participants.

If the population variance is unknown, then a degree of freedom is lost in the calculation of sample variance.

In a contingency table, what does the degrees of freedom indicate?

Suppose that a study compares the means of two groups. There are 40 males in Group 1 and 35 females in Group 2. The degrees of freedom for this study when using the t-test for the difference between means is:

Based on the information in Question 1, what were the degrees of freedom (DF) for the interaction of color and style, C?

What concept do "degrees of freedom" represent in statistical analysis?
