In general, I remembered most of the overall concepts from STAT 314. However, I forogt a lot of the specific details. For example, even though I remembered what confidence intervals and hypothesis test were and how to interpret them, I needed a reminder on how to actually calculate them. Looking back at my notes from last semester, I found all the formulas to calculate the intervals and p-values, as well as several R commands which I had forgoten, such as pt() which gives the p-value for a test stat for the mean where the variance is unknown, and t.test() which does all of the calcualtions for a t-test given the data. After not having used R for a while, I had forgotten most of the commands and a lot of the syntax, but after going through my work from STAT 314, it was easy to remember a lot of it. Also, it is very helpful that in R, if you type a “?” before the command, R provides all of the information regarding how to use the function.
