IASSC Exam ICBB Topic 6 Question 79 Discussion

Actual exam question for IASSC's ICBB exam

Question #: 79
Topic #: 6

[All ICBB Questions]

What conclusion is most correct about the Experimental Design shown here with the response in the far right column?

ANo factor has enough statistical confidence greater than 95% to have an impact on the response rate

BConstant, Adv and Bev are the only factors statistically affecting the response rate with 95% confidence or more

CIf the Adv is increased from the low level to the high level, the response rate increases

DThe response level is statistically concluded to only need the Adv and Bev factors set at the low level to get the largest response rate

EThis design does not have enough experimental runs to conclude anything as evidenced by the lack of P-values in the MINITABTM output

Wait, did they just ask us to interpret a MINITAB output with no p-values? That's like trying to read tea leaves to predict the stock market.

Ha! I bet the person who wrote this question was just trying to trick us. Of course, option A is the right answer - these results are about as clear as mud.

Yeah, this Experimental Design is definitely tricky to interpret.

I agree, it seems like no factor has enough statistical confidence.

I think option A is correct, these results are confusing.

Hmm, I'm not too sure about this one. The lack of p-values is a bit concerning, so I'm leaning towards option E. Maybe I should have paid more attention in my design of experiments class.

Definitely, we need to make sure we have enough data to draw meaningful conclusions.

Maybe we should revisit our design of experiments notes to understand this better.

Yeah, I agree. Without enough experimental runs, it's hard to draw any conclusions.

I think option E is the most correct, the lack of p-values is a red flag.

Option D seems enticing, but I'm not sure the design has enough power to make such a strong conclusion. It's always best to be cautious with these types of analyses.

This looks like a tricky experimental design question. I think option B is the correct answer, as the results show that Adv and Bev are the only factors with statistically significant effects at the 95% confidence level.

Yes, it looks like Adv and Bev are the main factors affecting the response rate according to the statistical analysis.

I agree, option B seems to be the most correct conclusion based on the experimental design.

But option B states that only Constant, Adv, and Bev are statistically affecting the response rate, while option D suggests that only Adv and Bev at low level are needed for the largest response rate.
