To calculate the total number of participants in a study, you typically sum the number of participants in each group or condition. Degrees of freedom (df) can be calculated as the total number of participants minus the number of groups (df = N - k, where N is the total number of participants and k is the number of groups). Sum of squares (SS) is calculated by taking the difference between each participant's score and the overall mean, squaring those differences, and then summing them up. In ANOVA, the total sum of squares (SST) is the sum of the between-group sum of squares and the within-group sum of squares.
An ultramarathon is technically defined as any distance longer than the standard 26.2 mile (42.195) marathon. The 50 km race is usually considered the shortest ultramarathon with distances from 30-100 miles very common.
