Take Quiz You are comparing weather delays of two airlines, Frontier (which flies primarily out of Denver Colorado) and Southwest (which flies primarily out of Phoenix Arizona). You look at flights out of Denver, Phoenix, and Seattle, and for each airport Frontier has less weather delays on average. When you look at all the data simultaneously, you find that Southwest has less delays on average. Explain how this apparent paradox can occur. (Note: Phoenix is in a desert climate with few extreme weather situations, while Denver is in a mountainous region with heavy snowfalls in winter) Exit
