Answers
1) There is a difference in how many errors people make when driving under control conditions, speeding, and texting (F (2,10) = 11.20, p < 0.05, eta squared = 0.36).
2) There is no difference in how much people want to go on vacation to Europe, Asia, South America, or Africa(F (3,9) = 2.53, p > 0.05, eta squared = 0.39).
