draft statistics

I took ResEcon statistics in my Fall semester of Sophomore year. Unfortunately, I do not remember a lot about statistics. We learned about different methods of sampling. These include stratified random, simple random, cluster, and systemic sampling. We focused a lot on graphs and statistical analysis. This included understanding residuals and correlation, and linear regression. I do not remember much detail about each specific concept. We spent a good amount of the semester on probability which was pretty basic. I know a lot about probability from learning it all throughout middle school and high school. We learned about how to use p value and degrees of freedom. I do not remember the equations we used, but I know there were a few.
