C makes the most sense, but I get the confusion!

I thought it was about distance, like D?

D) Distance between features? More like distance between my brain cells trying to remember this stuff!

I always get k-means and k-nearest neighbors mixed up. Hopefully, the exam doesn't have both!

I definitely recall k being linked to clusters in k-means, but I wonder if it could also refer to something else in a different context.

I’m a bit confused; I thought k might relate to data splits, but now I’m leaning towards clusters after reviewing my notes.

I remember practicing a question about k-means, and I’m pretty sure k is the number of clusters. That sounds right.

I think k represents the number of clusters, but I’m not entirely sure. It could be something else.

The k-means algorithm is all about partitioning the data into k clusters, so I'm pretty sure the answer is C) Number of clusters. That's a key part of how the algorithm works, so I think I've got this one figured out.

I'm a little confused on this one. Is k the number of data splits or the distance between features? I'll have to review my notes on k-means to be sure. Hopefully I can narrow it down during the exam.

Okay, I've got this. The k in k-means stands for the number of clusters we want the algorithm to find. So the correct answer has to be C) Number of clusters. I'm feeling pretty confident about that.

Hmm, I'm a bit unsure about this one. I know k-means has something to do with clustering, but I can't quite remember if k represents the number of clusters or something else. I'll have to think this through carefully.

I think the answer is C) Number of clusters. The k-means model is all about grouping data into k clusters, so that seems like the most logical interpretation.
