I've got a two-way analysis of this question - it's either B or D, and if I'm wrong, I'll be seeing double!

Hmm, let me think about this... I'm gonna go with option C, just because it sounds the most like a secret code. Who doesn't love a good rc-1 equation, am I right?

I agree with you, option C) rc-1 does sound like a secret code!

Wow, this question is as straightforward as a one-way street. I say go with option B, because it just makes sense mathematically.

Ah, the classic two-way ANOVA question. I'm going with option D. Why? Because it's the only one that includes the '2' for the 2 observations per cell. Simple logic, right?

Yeah, that's a good point. Option D seems like the most logical choice.

Hmm, let's see... Since there are r levels for one variable and c levels for the second, with 2 observations per cell, the degree of freedom for interaction should be (r-1)(c-1). Option B looks good to me!
