Systems Engineering has terminology for this distinction.
Verification is "does this thing do what I asked it to do".
Validation is "did I ask it to do the right thing".
Verification is "does this thing do what I asked it to do".
Validation is "did I ask it to do the right thing".
verification refers to "is this dataset clean?" or the more precise "does this dataset confirm my assumptions about what a what a correct dataset should be given its focus"
validation refers to "can it answer my questions?" or the more rigorous "can I test my hypotheses against this dataset?"
So I find this interesting (but in hindsight unsurprising) that similar definitions are used in other fields. Would you have a source for your defintions?
