The purpose of this data is to evaluate the performance for each grade level, type of school, or geographic location.

Assignment 7-SOCR Website

I really believe that this website will be helpful to our class. An interesting feature I found in this website is the "Distributions" tab at the top of the website. I found this very interesting because it shows you different types of distributions and I believe this will be very helpful later on, as it shows you many different distributions.

Another feauture that I found helpful was the "Probability & Statistics EBook". This is also found at the top of the website. This will really help me and my classmates because it includes material from the textbook. We can even use it now because it has two chapters based on probability, chapters 4and 5. It gives more examples on the subject that can be very helpful.
