A Brief Introduction to Probability and Statistics
Welcome to Statistics Help Online. This is a brief introduction to probability theory and statistics. There are many different expositions of statistical analysis online. I try to emphasize understanding statistics fundamentals, rather than giving a litany of tests that can be used. This is the most important thing for those seeking statistics help. Statistics is one of the most often used technical tools and it is also the most often misapplied one. I try to give you an overview of what it's all about and how to avoid misapplying it.
