I like that Ms. Thiele gives a real life example that is both interesting and easy to follow with this problem. Her definition of a z-score was easy to understand but it would be nice if she better explained the variables that are involved in solving the problem. What is the point of deviation? Why is the average number of home runs important in solving this problem? A little more explanation is all this video is missing.

I really like that this video shows a real life application of statistics. I also like that the video has a little bit of video, then the math, then a bit more video. It is creative and makes the video easy to pay attention to. The music at the end is introduced a bit abruptly, and the speaking could be a bit more clear, but otherwise this video is great.

The subject of statistics provides a great opportunity to apply math to a real-world situation, and you've done that wonderfully here.  Including real clips of Babe Ruth enhance this connection.  Areas of technical growth would be to fade the music in a litter better in the last moments (it was a little jarring), redoing some of the writing to make the numbers clearer and zooming in to the Babe Ruth videos to eliminate the timeline at the bottom.
