Overview of Nonparametric
Data Analysis Techniques
The objective of this course
is to acquaint students with the basic ideas, applicability, and methods of nonparametric data analysis.
After an introductory overview of fundamental concepts,
students will learn ten nonparametric analysis methods.
The course will be
laboratory-based. Use of the MINITAB™
statistical software package will be demonstrated using data from case studies.
Guidelines for interpreting MINITAB™ output analytically will be presented.
Students are encouraged to bring their own data analysis problems to the class
for discussion.
