While I respect what Fester's trying to do here, SWulfe is correct. This poll is not scientifically valid, and it may not in any way be generalized to the total AH population.
There are several reasons for that. First, it
does not consist of a random samping of players. Asking a number of pilots who are flying for a one hour period of time on one particular day hardly constitutes randomness. It likely excludes foreign players, those who work at night, and just about everyone else who for one reason or another does not play on Tuesday evenings. One could reasonably argue that any of these groups significantly differ from the one present that night in views toward in-tower radar.
Second, and going along with the randomness issue,
this is a self-selected sample. Rather than choosing a random sample of players from the MA and asking their opinions, Fester asked all players and recorded only the answers of those who responded. It's entirely possible, as SWulfe has attempted to show, that those who chose to respond are not representative of the general population of players. I find that argument compelling. Even a popup screen asking all players what they think of this issue potentially suffers from self-selection bias if players can close down the questionnaire without responding.
Hope that helps.
