# STAT 301

### Probability and Statistics

**Catalog Description:** Probability and statistics are areas of science that use quantitative procedures and methods that are designed to help in estimation, inference, and decision making processes. This course will provide the student with a variety of mathematical tools that help them make informed intelligent decisions when there is uncertainty in a situation.

**Total Credits:** 3

Software: I will not use any statistical software explicitly. However, we will familiarize ourselves with R and use R code on calculating several quantities. Previous exposure to R is not required. R is an open source and free software that you can download from http://www.r-project.org/ but I recommend to use R with the graphical user interface RStudio. Computers in student computing labs are equipped with RStudio. You can download Rstudio from https://www.rstudio.com/.
