Percentage of missing values is also important, but not the only one.

Wait, can you really just use the mode for feature drift? Seems too simple.

The mode is definitely a key statistic for categorical data!

I vaguely remember that the percentage of missing values can indicate drift, but I'm not confident if it's the best choice here.

I feel like the answer might be C since it includes multiple aspects of monitoring, but I can't recall if all of them are necessary.

I think we practiced a question about feature drift, and the mode was definitely mentioned as important.

I'd go with the percentage of missing values. That's a simple but important metric to keep an eye on, as changes there could indicate issues with data collection or processing.

The mode, number of unique values, and percentage of missing values seem like a good set of statistics to track. That would give you a pretty comprehensive view of any changes in the categorical feature over time.

I'm a bit unsure about this one. I know the mode is a measure of central tendency, but I'm not sure if it's the best for monitoring drift. Maybe the number of unique values or percentage of missing values would be better?

I think the mode is a good simple statistic to monitor for categorical feature drift. It gives a sense of the most common value, which could change over time.

I'm leaning towards the number of unique values as the best option here. Tracking how the diversity of the feature changes over time could be a useful way to detect drift.

This is a tricky one. There are a few options that seem relevant, but I'm not sure which one is the best fit. I'll need to think through the requirements step-by-step to make sure I select the right answer.

I'm a bit unsure about the third one, 'not' not in 'in'. I'll need to double-check the logic on that one.

Hmm, I wonder if the mode is the most suitable statistic for monitoring categorical feature drift. Maybe we need to consider the number of unique values and the percentage of missing values too. Just a thought.

The mode? Really? I thought we were supposed to monitor the number of unique values and missing values. This is a no-brainer, folks. Option C is the way to go.
