I thought it was 32 runs for a 6-factor design?

Totally agree, 16 runs is way too few!

Wait, isn't it 64 runs for full factorial?

That's true, 2^6 gives us 64 runs.

I feel like I might be mixing up the designs, but I thought 6 factors would definitely require more than 16 runs for a full factorial.

I practiced a similar question, and I think it was about 4 factors needing 16 runs, so maybe this one is also true?

I’m not sure, but I remember something about needing fewer runs if we’re only looking at main effects. Could it be false?

I think it’s true because a Level 2 Design means we have 2 levels for each factor, and with 6 factors, it sounds like we would need 2^6 runs.

Ah yes, I know this type of question. The number of runs is 2 raised to the power of the number of factors. So for 6 factors, that would be 2^6 = 64 runs. I'm confident I've got this one.

I'm a bit confused on this one. Factorial experiments can get complicated, especially with multiple factors. I'll need to review my notes and examples to work through this step-by-step.

I remember learning about these factorial designs in class. I think the key is to determine the number of factors and the number of levels per factor. That should give me the total number of runs needed.

Okay, a Level 2 design with 6 factors... I'm pretty sure that would require 64 runs, not 16. Let me double-check the formula.

Hmm, this seems like a tricky one. I'll need to think through the factorial experiment design principles to figure this out.

A Level 2 Design with 6 factors? That's a lot of moving parts! Better bring my abacus to keep track of all those interactions.

False. With 6 factors at level 2, it would actually require 2^6 = 64 runs, not 16.

True. Each factor at level 2 requires 2 runs, so 2^6 = 64 runs total.
