Mazda 5 2014: MOT failure rate for its age
30.6% of 3,613 MOT tests of the Mazda 5 first registered in 2014 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 93.5 (95% CI 88.0–99.0; 100 = normal for this model at that age): the 2014 Mazda 5 fails less often than other build years of the same model at the same age. This is a rough estimate from a smaller sample.
| Measure | Value | Unit | Compared with | Years | Tests |

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.
