Out of curiosity, could you add which country you are from? I think in general there's similarities everywhere.
In Belgium (Gent to be more specific) where I'm from, there is a high cultural degree of critical thinking, and if I handed in a report like that, with the accompanying numbers, our teacher would not have given it a failing grade. Especially if the report was accompanied with either a written or verbal disclaimer mentioning the limitations of the measuring equipment and that the results didn't match your expectations.
