Now that we know what confidence intervals are, let's dive into how to calculate them. There are different methods for calculating confidence intervals, and I'll walk you through the most common ones. From there, we'll explore how to apply these methods to real-world user research scenarios.

While calculating confidence intervals may seem straightforward, there are some common pitfalls to watch out for. In this section, we'll cover some of the most common mistakes and how to avoid them. By understanding these pitfalls, you'll be able to calculate confidence intervals with more accuracy and confidence.

Once you've mastered the basics of calculating confidence intervals, it's time to take it to the next level. In this section, we'll explore advanced techniques for calculating confidence intervals, including Bayesian methods and bootstrapping. I'll share my expertise on when to use these techniques and how to apply them to your user research.
