EXAMPLE 2: One-Way ANOVA A neuropsychologist was interested in how monkeys learn to perform a task. The task was to retrieve a coconut from the opposite side of a river. Fifteen wild monkeys were assignment to one of three conditions: observing a monkey {they watched another monkey retrieve the coconut by building a bridge across the stream}, observing a human {they watched a human solve the task}, and banana reward {they were allowed to do what they wanted but every time they engaged in behavior that facilitated solving the task they were rewarded with a banana). After learning the monkeys were required to solve the problem again and the time taken to solve the problem was measured. Carry out a one-way ANOVA by hand to test the hypothesis that some forms of learning are more successful than others. Can you suggest some follow-up comparisons {with weights].
