The type of sampling used is not e or c or a it is either b or d which one do you think it is?

buttermequeasy · Answer

I think it could be convenience sampling, seeing as they are choosing 120 random flights.

anonymous · Answer

but if it is convenience wouldn't they just choose the next 120 flights?

anonymous · Answer

I think that it would make sense for it to be choice b because it is a random simple selection.

buttermequeasy · Answer

Actually, yes, you're right. I think it's simple random because every person that boards Continental Airlines has an equal chance of being part of the surveys
