I do not get the same answer that the test graded me on for this practice question.
I get answer (C), and here is the math I used - please help point out where my math went wrong...
- 2 level 5 factor full factorial test = 2^5 = (2 * 2 * 2 * 2 * 2) = 32
- multiply above for each replicate (2), and I get = 32 x 2 = 64.
- Now, that means a 1/2 fractional would be 64/2 tests = 32 tests. 32!= 16, so keep looking.
- A 1/4 fractional would be 64/4 tests = 16 tests. 16 = 16, so answer is (C). Or...
