A great compilation of statistical tests to use in ecology. The reason these tests are good for ecology is because they allow you to express the results of experiments and observations with many factors and many possible outcomes. In ecology the data is varied over time, size scale, temperature, and other continuous variables that are hard to divide up, and this book helps you do that.
I would not call this book a "Primer." It was the main textbook for a statistics course I took in college, and i had previously taken AP statistics in high school. Students with no previous experience in statistics had a much harder time with it. The writing is mostly solid, but there were times when the concepts were not explained in a way that was clear to me. They could have done a slightly better job considering the state of mind of someone who is unfamiliar with statistics.
