IDTH 360  01  Advanced Statistical Software            
Description of course Genetics B/ Lab: 
CRN: 43431
Instructor: German J. Pliego Hernandez
This course introduces students to an advanced statistical software package to effectively apply statistical methods, in general. Students create data sets from raw data files, create variables within a data set, append and/or modify data sets, create subsets, then apply a whole host of statistical procedures, create graphs and produce reports. The course will be based on several leading advanced statistical software packages, which will be chosen from semester to semester to match the needs of the community.
Prerequisites: MATH 113, STAT 220 Statistics I or STAT 314 Math Statistics (MATH 314)
