Orthogonal? More like or-tho-gonal, am I right? Anyone? Bueller?

True, unless the variables are measuring the weight of elephants. Then it's false, obviously.

Wait, aren't orthogonal designs something to do with gardening? I'm so confused...

I agree with Jenelle. The definition of orthogonal design is when all possible variable pairs sum to zero, so the answer is True.

False, this sounds like a trick question. Orthogonal designs have to meet more complex criteria.

I think it's False. Just because the variable pairs sum to zero doesn't necessarily mean the design is orthogonal.
