Guide to Validity Threats in AB Testing for PMI-ACP

The term Validity Threats in AB testing refers to the factors that can affect the validity of the test results.
The main types of validity threats are:
1. Internal Validity Threats: These are errors that occur within the test itself.
2. External Validity Threats: These are errors that occur due to the environment or conditions outside of the test.
3. Construct Validity Threats: Errors occur when the test doesn't accurately measure the concept or construct it was intended to measure.
4. Conclusion Validity Threats: Errors occur due to conclusions drawn from the results.

Understanding these concepts is important for your PMI-ACP exam, especially when conducting or interpreting AB tests.

Validity Threats practice test

Validity threats refer to the factors that can jeopardize the accuracy of the A/B test results. They include history effect (external factors influencing users' behavior during the test), selection bias (non-random distribution of users into groups), instrumentation effect (changes in measuring system), and novelty effect (users responding positively to any change because it's new). Awareness and mitigation of these threats improve the quality and reliability of your test results.
