We worked together in class during the work sessions and spoke outside of class about the assignment as well. I also took the instructions from the [[Week 10]] assignment page and modified them slightly to be specific to my analysis.
 While I worked with the people noted above, this individual journal entry was completed by me and not copied from another source.
