Research Question: Is there a difference in VO₂max [mL/(kg*min)] between Olympic rowers, Olympic cross-country skiers, and Olympic swimmers?

Design: A sample of 20 Olympic rowers, 20 Olympic cross-country skiers, and 20 Olympic swimmers were recruited. Each individual performed a single VO₂max test.

Shapiro-Wilk test

Olympic rowers: p = 0.37

Olympic cross-country skiers: p = 0.12

Olympic swimmers: p = 0.03

Levene's test: p = 0.01

From the following information which test is appropriate ?

(a) Independent ANOVA

(b) Kruskal-Wallis

(c) Repeated-measures ANOVA

(d) Friedman test
