This is our final project this semester. It summarizes the most important statistical tests you
learned in my class. It will also show you, once again, how we can apply our knowledge to
business situations. This project will be of value to any real estate

Types of Variables
Okay so now I'm going to talk about different types of Variables. So, you know first of all, what is
a variable? Well, a Variable is a property that can take on many values. Like for example

Sampling methods (New Zealand accent)
Sampling: Simple, Convenience, Systematic, Cluster, and Stratified.
To find things out about a population of interest, it is common practice to take a sample. A sample
