A/B testing, also known as split tests, is a controlled experiment with two variants, A and B in Web Analytics where two or more variants of a page are shown to users at random, and statistical analysis is used to determine which variation performs better for a given conversion goal.
The [course_title] course teaches you how to choose and characterise metrics to evaluate your experiments. You will learn to design experiment with enough statistical power, and then analyse the results and draw valid conclusions.
Assessment
This course does not involve any written exams. Students need to answer 5 assignment questions to complete the course, the answers will be in the form of written work in pdf or word. Students can write the answers in their own time. Each answer needs to be 200 words (1 Page). Once the answers are submitted, the tutor will check and assess the work.
