What is the range of the Zip 11 confidence score?

• A. 0 to 100
• B. 1 to 100
• C. -100 to 100
• D. 0 to 50

Answer: (D)

The main idea is that confidence scores are bounded and nonnegative. In this system, the Zip 11 confidence score is defined to never go below 0 and never exceed 50. That means 0 represents no confidence, while 50 is the highest confidence achievable within this scale. The design purposefully uses a capped, nonnegative range rather than a 0–100 percentage; this keeps the score compact, easy to display, and leaves room for other scoring components if needed. So the valid range is 0 to 50.
