Lennard is deciding whether to purchase a wireless speaker from a major online retailer. He looks at the reviews for the speaker and notices that out of 100 reviews posted (with possible range of 1−5 stars), 99 reviews are 4 or 5 stars and only 1 review is 1 star-rated. He does, however, notice that the 1 star-rated review was posted very recently - just over the past few weeks. Nevertheless, the average overall rating for the product is 4.7 and Lennard decides to purchase the speaker. Why is the average review statistic misleading in this case?
