Lets face it, statistics wasn't your favorite course in college. It didn't seem to connect with real life, or even ground water science. But now you need to make sense of your data. This workshop will help those jilted by statistics to be reconciled.

We will look together at basic principles of data analysis, including when to transform data and why, how to handle outliers, what hypothesis tests are good for, and how to build a good regression
equation. Advantages of newer nonparametric and permutation tests for scientific applications will be highlighted. Common pitfalls of traditional methods will be discussed. Attending this workshop will clear up misconceptions, point to further resources, and get you heading in the right direction.
