Shannon's Entropy

Using Shannon's Entropy in Excel makes making diagrams easy and organized. I think this would be helpful for teachers who are trying to show how their students perform and the flow of their classrooms. I think the diagram is also very important in understanding search engines, such as Google because it is like a chain of events where you have to input a search query and it will narrow your results based on what you say is true about what you are looking for or not.
