Jason Newsom's
USP 654 Data Analysis II

 

 

Description

This course takes an applied approach to statistical analysis and research methodology and is the second in a two-course sequence. The goal is to provide students with statistical background, conceptual understanding, technical writing skills, computer application, and the ability to apply these skills to realistic data analysis problems and research designs. Topics include simple regression and correlation, multiple regression, and logistic regression. The laboratory (USP 654L) must be taken concurrently. Recommended prerequisite: USP 634 Data Analysis or an equivalent course approved by the instructor and prior experience with statistical software.
