Inaccurate means not exactly right. Inaccurate figures, wildly inaccurate, an inaccurate account.
It is a measured word — it says wrong without saying dishonest, which is why corrections and retractions reach for it. In measurement, accuracy is closeness to the true value and precision is repeatability, so a reading can be precise and inaccurate at once. Note that the Latin root means done with care, so inaccurate is literally careless.
