What is the course about?

A/B Testing

The course A/B Testing is an online class provided by Udacity. The skill level of the course is Intermediate. It may be possible to receive a verified certification or use the course to prepare for a degree.

This course will cover the design and analysis of A/B tests, also known as split tests, which are online experiments used to test potential improvements to a website or mobile application. Two versions of the website are shown to different users – usually the existing website and a potential change. Then, the results are analyzed to determine whether the change is an improvement worth launching. This course will cover how to choose and characterize metrics to evaluate your experiments, how to design an experiment with enough statistical power, how to analyze the results and draw valid conclusions, and how to ensure that the the participants of your experiments are adequately protected.

Online Experiment Design and Analysis

Overview of A/B Testing
Policy and Ethics for Experiments
Choosing and Characterizing Metrics
Designing an Experiment
Analyzing Results

This lesson will cover what A/B testing is and what it can be used for.
How to construct a binomial confidence interval for the results.
How to decide whether the change is worth the launch cost.
How to make sure the participants of your experiments are adequately protected.
What questions you should be asking regarding the ethicality of experiments.
The four main ethics principles to consider when designing experiments.
Learn techniques for brainstorming metrics.
What to do when you can’t measure directly.
Characteristics to consider when validating metrics.
How to choose which users will be in your experiment and control group.
When to limit your experiment to a subset of your entire user base.
Design decisions affect the size of your experiment.
How to analyze the results of your experiments.
Run sanity checks to catch problems with the experiment set-up.
Check conclusions with multiple methods, including a binomial sign test.

This course requires introductory knowledge of descriptive and inferential statistics. If you haven’t learned these topics, or need a refresher, they are covered in the Udacity courses Inferential Statistics and Descriptive Statistics.
Prior experience with A/B testing is not required, and neither is programming knowledge.
See the Technology Requirements for using Udacity.

A/B testing, or split testing, is used by companies like Google, Microsoft, Amazon, Ebay/Paypal, Netflix, and numerous others to decide which changes are worth launching. By using A/B tests to make decisions, you can base your decisions on actual data, rather than relying on intuition or HiPPO’s – the highest paid person’s opinion! Designing good A/B tests and drawing valid conclusions can be difficult. You can almost never measure exactly what you want to know (such as whether the users are “happier” on one version of the site), so you need to find good proxies. You need sanity checks to make sure your experimental set-up isn’t flawed, and you need to use a variety of statistical techniques to make sure the results you’re seeing aren’t due to chance. This course will walk you through the entire process. At the end, you will be ready to help businesses small or large make crucial decisions that could significantly affect their future!
