"Excludability's Impact on Accurate A/B Testing"

Excludability

Excludability refers to the ability of a good or service to be restricted to certain individuals or groups. A good or service is considered excludable if it is possible to prevent people who have not paid for it from accessing or using it. Examples of excludable goods and services include private property, cable television, and movie theaters.

When it comes to A/B testing on the web and in mobile, excludability can impact the accuracy and validity of the results. If a test is not properly designed to exclude certain users or groups, the results may be skewed or inaccurate. For example, if a website is testing a new feature that is only relevant to a specific demographic, such as users in a certain geographic location, the test should be designed to exclude users outside of that location. Otherwise, the results may be influenced by users who are not part of the target demographic and may not accurately reflect the impact of the new feature on the intended audience.
