CMIYC? Sounds made up, is that even a real method?

Scalers are not for outlier detection, just normalization!

I’m leaning towards Z-Score too; it’s like a standard way to identify outliers based on standard deviations, right?

BOXI sounds familiar, but I can't recall if it's actually a method for outlier detection or something else.

I remember practicing with a question about outliers, and I feel like Scaler was mentioned, but it doesn't seem right for this.

I think Z-Score is the method we learned for detecting outliers, but I'm not completely sure if it's the only one.

Ah, I remember this now! The Z-Score method is definitely the way to go for detecting outliers in machine learning datasets. Glad I brushed up on that before the exam.

Okay, let me see. I think the Z-Score method is used to identify outliers by calculating the standard deviation from the mean. That sounds right, but I'll double-check my notes just to be sure.

I'm pretty sure the answer is Z-Score, that's the method we learned for detecting outliers in the machine learning module.

Hmm, I'm a bit unsure on this one. I know we covered outlier detection, but I can't quite remember the specific method. I'll have to think this through carefully.

I'm a bit confused on this one. The options seem to cover different aspects of the TOGAF process, but I'm not sure which one specifically relates to the Preliminary Phase.

C) BOXI and D) CMIYC? Really? Those sound more like secret agent code names than ML techniques. Nice try, exam writer!
