What you’ll learn to do: State the five assumptions, null, and alternative hypotheses for a one-way ANOVA

Is the average amount of money spent by Olympic athletes on their training the same for all water sports (pool swimming, diving, water polo, synchronized swimming, open-water swimming)? To answer this question, we would want to compare five means. Rather than doing separate t-tests for each different pair of water sports, we will do an analysis on all five means called an Analysis of Variance or ANOVA.
