Welcome  <  Begin  <  Unit 2  >  Section 1 
Topics Covered 
Statistical inference deals with decision making and prediction based on sample data. In this Unit we will explore the basic concepts dealing with estimating population parameters and testing of hypotheses. The basic one and two sample methods discussed here will be used throughout the remainder of this course. A good understanding of the basic statistical approaches to estimation and hypothesis testing will allow you to extend your statistical toolbox with new methods. Note that all of the statistical methods discussed here are aimed at analysis of continuous random variables. Discrete and categorical random variables will be discussed at the end of the next Unit.
