Which item is NOT typically included in an A/B testing plan?

• A. Overview of the test
• B. Channel being tested
• C. Color of the font in assets
• D. Confidence level

Answer: (C)

A/B testing plans focus on defining the experiment’s structure: what you’re testing, where it runs, how long it lasts, how traffic is split, and how you’ll measure and decide outcomes. The overview of the test sets the purpose and scope so everyone agrees on the objective. The channel being tested identifies the place for the experiment—website, app, email, etc.—so the plan covers the right environment and audience. The confidence level establishes how reliable your results need to be before you declare a winner, guiding sample size and duration decisions. The color of the font in assets, however, is a granular design detail—the exact visual treatment used in the creative. That kind of specification belongs to the execution of the variants, not the planning framework itself. If you decide to test font color, you’d treat color as the variable expressed in the variants, but the plan typically focuses on the variable category and how success will be measured rather than prescribing exact color values. So this item isn’t a fundamental planning component, while the others are essential for structuring the test and interpreting results.
