Henry Garner is a graduate from the University of Oxford and an experienced developer, CTO, and coach. He started his technical career at Britain's largest telecoms provider, BT, working with a traditional data warehouse infrastructure. As a part of a small team for 3 years, he built sophisticated data models to derive insight from raw data and use web applications to present the results. These applications were used internally by senior executives and operatives to track both business and systems performance. He then went on to co-found Likely, a social media analytics start-up. As the CTO, he set the technical direction, leading to the introduction of an event-based append-only data pipeline modeled after the Lambda architecture. He adopted Clojure in 2011 and led a hybrid team of programmers and data scientists, building content recommendation engines based on collaborative filtering and clustering techniques. He developed a syllabus and copresented a series of evening classes from Likely's offices for professional developers who wanted to learn Clojure. Henry now works with growing businesses, consulting in both a development and technical leadership capacity. He presents regularly at seminars and Clojure meetups in and around London.

Rather than launching it to all users at once, AcmeContent would like to test the site on a small sample of visitors first. We've educated them about sample bias, and as a result, the web team diverts a random 5 percent of the site traffic to the new site for one day. The result is provided to us as a single text file containing all the day's traffic. Each row shows the dwell time for a visitor who is given a value of either "0" if they used the original site design, or "1" if they saw the new (and hopefully improved) site.

Performing a z-test

While testing with the confidence intervals previously, we had a single population mean to compare to.

With z-testing, we have the option of comparing...

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar? We did, then collated those deliberations into absurd research articles with fake figures and methodologies inspired by even more fictionally absurd studies.
