Ford B-MAX 2018: MOT failure rate for its age
18.0% of 2,841 MOT tests of the Ford B-MAX first registered in 2018 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 117.8 (95% CI 107.6–128.0; 100 = normal for this model at that age): the 2018 Ford B-MAX fails more often than other build years of the same model at the same age. This is a rough estimate from a smaller sample.

| Age | Tests | Failed, % | 95% interval | Normal for this model at that age, % | Index (100 = normal) |
|---|---|---|---|---|---|
| 3 | 752 | 10 | 8–12.3 | 10.6 | 94.1 |
| 4 | 704 | 12.8 | 10.5–15.5 | 12.7 | 100.3 |

How every figure is calculated: methodology. Age, test year and build year are tied together (age = test year − build year), so the test-year level is taken as observed, not estimated.
