<p>How hard are these classes? </p>
<p>I'm a bio major and took math 1A and 1B last year, and AP stats in high school. I don't really want to go through learning about p-values and stuff like that again, but I'm worried about jumping on board an upper-div stats class. 133 especially is confusing me because there are no prerequisites mentioned on the catalog description, but just based on the course description it sounds pretty intense. Any advice?</p>
<p>Stat 133 is a programming class where you learn to program using R - a statistical software widely used in research. It’s a required class if you’re a Stat major. There’s not much math involved, you just learn how to do certain kinds of analysis (e.g. cluster analysis, smoothing, aov etc), how to create graphics (2d/3d plots), working with databases and cgi in R. You don’t need any previous programming experience since R is easy to learn. It’s pretty much the easiest upper div Stats class since it’s not even really programming, it’s just learning how to use different functions in R. If you take it with Kaufman, it’s just weekly programming assignments, a final project and a short final testing you on some R commands.</p>
<p>I’m not familiar with 131a but from the description, it sounds like it might suit you better since you’re a bio major.</p>
