2. Taylor is curious to know how different types of music affects how long it takes someone to finish their homework. She tests 4 groups of 3 12 year olds. The first group listens to nothing. The 2nd group listens to classical, the 3rd listens to pop music, and the 4th listens to heavy metal. Each group then reads 20 pages of the same book and answers the same set of 20 math questions. She times each group and compares.
