Android Market now breaks down user reviews
The new statistics, found under the screenshot of the app, would seem to be useful for those apps that have not received much feedback and where a few well-placed stars could change the average score. Besides, the average score doesn't reveal what people are thinking above or below that average. Knowing how many users have ranked an app 1-star or 5-stars could make the difference in whether or not you decide to install it. Of course, you can quickly uninstall something that you don't like and get a refund, but you will have wasted the one thing in this world that no one gets a refund on...time.
