PPT-What Is Normality?

Explaining the Normal Distribution Preliminaries How to describe data Discussion Question How do we describe data in Statistics In this course the way we describe data is by using the CUSS Method We look at these characteristics.

As such, our statistics have Solutions. A.  . solution.  . is a homogeneous mixture of two or more substance. A solution is generally composed of two substances.
