So, in this chapter, we learned how null hypothesis testing can help us structure our analyses. Having a well thought out and standard procedure also ensures that we are thorough in our analysis. For example, in this chapter, we were forced to confront the ugly truths about the data we were working with, and that gave us insights into the results that we achieved later.
In the next chapter, we'll actually get a chance to use these techniques again, when we look at conducting A/B testing on websites.
