Welcome to the class website. You will have this website for checking homework assignments and getting help on stats topics as well as excel. We also use another website, edmodo.com, to turn in assignments.

Edmodo.com is similar to facebook, though it is developed specifically for classrooms (so not quite as riveting).

Go to edmodo.com right now and join using the following code:

period 6: gtc3m9

period 7: q4e4ll
