DRUK,
he only thing we can be sure of is whether Airline X was better/worse than Airline Y for any given metric, for example in the above stats for Oman Air we can tell that 19 airlines performed better than it did on CDAs (but not how much better).
Exactly, so I’d argue you’re not using ‘data’. You’re extrapolating back from the final results to try and determine what that data is.
