set. The data analyst needs to identify which columns are continuous in the data set.
What describes a continuous variable?
B vs C? I’m ruling out A since “never stops changing” is too vague and kinda weird wording. D is clearly off because it talks about categories, not continuous values. Between B and C, B talks about finite or countable values, which fits discrete variables better. Continuous variables should be able to take any value within a range — so uncountable sets, like in C. So C makes more sense here because continuous means you can have any decimal or fraction between numbers, not just countable points.
B tbh isn’t right because it says finite or countably infinite, which sounds more like discrete variables. D is about categorical variables, so that’s out. A is kinda vague and “never stops changing” doesn’t really capture the math behind continuous variables. C nails it with the idea of uncountable values in a range, which fits the definition of continuous variables best.
It’s C, since continuous means values can be any number in an interval, not just countable points.
I think the answer is C. Continuous variables can take any value within a range, so they have an uncountable number of possible values, unlike discrete variables that are countable. Does that make sense?
