Wait, so we're supposed to run 128 experiments just to test 4 factors? That's madness! I'm going to design my experiment with one factor at a time, that'll be way more efficient. *winks*

I'm going with C) 256. Wait, no, that can't be right... Ugh, I always get these factorial design questions mixed up! *grumbles*

Nah, I'm pretty sure it's D) 64. The question says there are no center points, so that means we only have the corner points with 2 replicates, right? Seems like the easiest answer to me.

So, the answer is definitely D) 64. It's a straightforward calculation based on the information given.

Yeah, that's correct. With 4 factors at 2 levels and 2 replicates for corner points, it adds up to 64 runs.

I think you're right, D) 64 makes sense since there are no center points in the design.

Hmm, I think the answer is B) 128. That's the number of experimental runs for a full factorial design with 4 factors at 2 levels, right? Plus 2 replicates for the corner points.

I'm not sure, but I think the answer might be C) 256. Can someone explain the rationale behind the correct answer?

I agree with Alisha, because for 4 factors at 2 levels with 2 replicates, the formula is 2^(number of factors) * number of replicates = 2^4 * 2 = 128.
