<h1>Part XI Overview<a href="Week12.html#Week12" class="anchor-section" aria-label="Anchor link to header"></a></h1>
<p>Part XI concludes this book with two topics that are important for applying and communicating statistical techniques.
The first topic is experimental design, which is introduced in <a href="Chapter_37.html#Chapter_37">Chapter 37</a>.
This chapter introduces a range of relevant issues to consider before collecting data.
It is not intended to comprehensive, but rather to help you avoid pitfalls that might arise during data analysis.
Without proper planning for data collection, statistical analysis can become unnecessarily complicated, inefficient, or worse!
Failure to consider relevant factors in experimental design might make it impossible to test the desired scientific hypothesis, thereby rendering data collection useless, at least for its intended purpose.
This is obviously something to avoid, so some discussion of experimental design is warranted.
The second topic is reporting statistics, which is introduced in <a href="Chapter_38.html#Chapter_38">Chapter 38</a>.
After conducting the statistical tests that are introduced throughout this book, it is important to be able to effectively communicate your results.
Chapter 38 briefly introduces the structure of scientific reporting and provides some guidelines for reporting statistics in the biological and environmental sciences.
These guidelines are not intended to be hard rules, but provide some examples of effective ways to report output from the major statistical tests introduced in this book, including ANOVA and its nonparametric alternatives, Chi-square tests, correlation coefficients, and linear regression output.
<a href="Chapter_39.html#Chapter_39">Chapter 39</a> finishes the book by demonstrating how to conduct these statistical tests in R.
Like the introduction to R in <a href="Chapter_36.html#Chapter_36">Chapter 36</a>, it uses a series of tasks to be completed.
The chapter works through how to open and view a dataset in R, then use R code to run ANOVAs, Chi-square tests, correlation tests, and simple and multiple linear regression.
It also demonstrates how to test key assumptions underlying statistical tests, such as the Shapiro-Wilk test and Levene test.
The dataset used in this chapter is yet another fig wasp example, which includes morphological measurements of fig wasps of five different species spread across multiple sites and trees.</p>
