In a repeated measures design, we are interested in comparing scores of the same group of participants under different conditions. This means that we have paired scores, and therefore the degrees of freedom are based on the number of pairs of scores minus one. This is calculated using the formula df = N - 1, where N is the number of pairs of scores. Therefore, the critical t value for a repeated measures design is based on the degrees of freedom calculated using this formula.
