IIBA CBDA Exam - Topic 4 Question 28 Discussion

Actual exam question for IIBA's CBDA exam
Question #: 28
Topic #: 4
[All CBDA Questions]

A lab is conducting a study on protein interactions. They have used the data to create a graph visualization. In graph visualization, what would an edge represent?

Show Suggested Answer Hide Answer
Suggested Answer: C

Covariance measures the directional relationship between the returns on two assets. A positive covariance means that asset returns move together while a negative covariance means they move inversely. Zero covariance indicates that the returns on the two assets move independently of each other. In the context of a scatter plot, zero covariance is represented by a plot where the points do not show any upward or downward trend but are rather scattered randomly on the graph with no discernible pattern.

Graph 4 displays such a pattern where there is no apparent relationship between the variables on the x and y axes, indicating that there is zero covariance between them.

Nope, just links! Edges are all about connections.

Yeah, I agree with the others. Edges are about connections, like how proteins interact. I just hope I remember that correctly during the exam!

I'm a bit confused. I thought edges might represent collections of data points, but now that I think about it, that doesn't really make sense.

I remember practicing a question similar to this, and I think edges definitely indicate some kind of interaction or relationship.

I think an edge represents a link between two data points, but I'm not completely sure. It feels like something we covered in class.

I feel pretty confident about this one. The explanation makes it clear that an edge represents the connection or relationship between two nodes in the graph visualization.

Okay, let me think this through. The question is asking about what an edge represents, so it's got to be one of the options given. I'm going to go with B - a link between two datapoints.

Hmm, I'm a bit unsure about this one. Is an edge really just a single datapoint, or is it the whole collection of datapoints and links?

This seems straightforward - an edge in a graph visualization must represent a link between two datapoints, right?

I'm just impressed they're using graph visualizations in a protein study. That's some serious data analysis going on. *whistles* Glad I didn't have to take this exam, though. I'll stick to my spreadsheets, thank you very much.

Hah, I can already picture the poor lab technicians trying to explain the difference between a node and an edge to their supervisor. Graph theory can get a bit tricky, but this question is a piece of cake.
