IIBA CBDA Exam - Topic 1 Question 2 Discussion

Actual exam question for IIBA's CBDA exam

Question #: 2
Topic #: 1

An analyst is doing a clinical study on the value of analyte among a large population of healthy people. The analyst is going to use a Gaussian Distribution to share the results. Which of the following represents a Gaussian Distribution?

Show Suggested Answer

Suggested Answer: B

The Gaussian distribution, also known as the normal distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean. In graph form, the Gaussian distribution will appear as a bell curve, which is the case with option A. It is characterized by its bell-shaped curve and is defined by the mean () and the standard deviation (). It is a common assumption for the distribution of independent, randomly generated variables.

I thought Gaussian had more variance options, interesting!

Definitely A, it looks like a classic bell curve!

I believe the answer is the one that shows the classic bell curve. I just hope I can identify it correctly under pressure!

I'm a bit confused about the options. I know that Gaussian distributions have specific properties, but I can't recall which one fits best.

I practiced a similar question last week, and I think the correct answer is the one that looks symmetrical around the mean.

I remember studying Gaussian distributions, but I'm not entirely sure which graph represents it. I think it should be bell-shaped, though.

Ah, I see now. Option B matches the classic bell-shaped Gaussian curve. The others don't have the right symmetry or shape.

Okay, let me think this through. A Gaussian distribution is symmetric, unimodal, and has a specific mathematical formula. I'll carefully compare the options to those characteristics.

Hmm, I'm a bit unsure about this one. I know Gaussian distributions are bell-shaped, but I'm not totally confident in identifying the right curve from the options.

This looks like a straightforward question about Gaussian distributions. I'll review the key properties of Gaussian distributions and match them to the options.

I'm pretty confident that billboard advertising would be considered a traditional marketing channel. It's been around for ages and is a classic form of advertising.

Hmm, this looks like a tricky one. I'll need to think through the Salesforce CMS and Experience Builder components carefully to figure out the right place to create the CMS collection.
