Introduction
This semester, I learned a lot more about political science than I ever thought I would. I
came into this class thinking that this would be a statistics class. I wasn
t too far off, but I had no
idea how much these process come into play in the political world. Polling is a major part of
politics, and a lot of what I learned this year makes polling possible. I
m a political science
major, so a lot of this may be very relevant to me if I continue to pursue a job in the political
world. Maybe one day I may use this material in my daily tasks. This was a really different class,
which I liked. It
s not your typical academic structure. I also thought R Studio was an awesome
thing to learn about. It still confuses me occasionally, but I find it fun to play around with. I hope
that in my next two years here at Ole Miss, I can revert back to some of the concepts that I
learned in this class as well. Despite it being really different, I am glad this is a required course
for political science students. I really enjoyed the change of pace. It was a great class.
