Totally agree, random samples are a must!
JA

I thought multiple locations were optional, not required.
HE

Wait, does the population really have to be homogeneous?
LE
Leah

I think the sample size being over 10 is also crucial.

Definitely need a random sample for significance!

I’m a bit confused about whether multiple locations are necessary for statistical significance. I feel like it might not be essential, but I could be wrong.
BR
Brice

I think we practiced a question similar to this, and I recall that having a homogeneous population is important, so maybe I and III are the right choices?

I'm not entirely sure, but I feel like the sample size being greater than 10 might not be enough on its own to ensure significance.

I remember discussing the importance of random sampling in class, so I think III is definitely one of the conditions.
TI

I'm a bit confused on this one. I know the random sample is important, but I'm not sure about the other conditions. I'll have to review my notes to make sure I understand this properly.

Hmm, this is a tricky one. I know the sample has to be random, but I'm not sure about the other requirements. I'll have to think this through carefully.

I'm pretty sure the key conditions are that the sample must be random and the population must be homogeneous. The sample size and multiple locations don't seem as critical.
BI

Okay, let me see. The population needs to be homogeneous, and the sample has to be random. I think those are the two main things to focus on for statistical significance.

Okay, I think I've got this. The question is asking which phase of the PDCA cycle assesses the effectiveness of the BCMS against the business continuity policy requirements. That sounds like it would be the "Check" phase, where you evaluate the results.

Wow, this exam is really testing our knowledge of statistical jargon. I'm going to go with C, II and III, and hope I don't end up with egg on my face.
CH
Cherry

Hmm, multiple locations? Isn't that just going to introduce more variability? I think I'll stick with C, II and III. Seems the most logical to me.
SA
Sabine

So, it looks like the correct answer is C, II and III.
ER
Erinn

Yes, both the sample size and randomness of the sample are important factors to consider.
KR
Kristeen

But doesn't the sample size also play a role in determining statistical significance?
JA
Jaclyn

I agree, having a random sample is crucial for statistical significance.
RE
Remona

Haha, 'must be greater than 10'? Seriously? I'm not a statistician, but that sounds like a pretty random requirement. I'll go with C, II and III.
CU
Curt
1 year ago
Yeah, I also chose C, II and III. It makes sense to have a random sample and a decent size.
MI
Mira

I agree, it helps to make sure the results are reliable.
ZO
Zona

I think the key is having a random sample, so I'll go with D, III and IV.
MA
Martha

I think the sample size requirement is to ensure accuracy.
ED
Eden
1 year ago
I'm not sure about the sample size, but I know the sample must be random. So I'll choose B, I and III.
SH
Sharee
1 year ago
I agree, the sample size requirement does seem arbitrary. I also think it's II and III, so I'll go with C.
LA
Lajuana
1 year ago
Homogeneous population? That's a new one. I think I'll go with B, I and III. Randomness is key, right?
MA
Ma
1 year ago
Wait, so the sample has to be random, but also from multiple locations? That seems contradictory. I'm going with C, II and III.
CH
Chau

User2: I agree, and the sample must also be random.
VI
Vicente

User1: I think the sample size must be greater than 10.
GI

But doesn't the sample size need to be greater than 10 for statistical significance?
LI
