Statistics, Hypothesis Testing, Regression

Course Overview


This course teaches participants the fundamental concepts and methods needed to organize and analyze data and make objective decisions based on the data. Participants will also learn to compare groups in order to determine whether they are statistically similar or not. Additionally, the course instructs in the development of mathematical models to predict outcomes and understand key factors affecting our processes. Knowledge of basic algebra is helpful. Computer software is utilized although an understanding of underlying concepts and methods is stressed.
