Databricks Certified Data Analyst Associate — Question 55
A data scientist has asked a data analyst to create histograms for every continuous variable in a data set. The data analyst needs to identify which columns are continuous in the data set.
What describes a continuous variable?
Answer options
- A. A quantitative variable that never stops changing
- B. A quantitative variable that can take on a finite or countably infinite set of values
- C. A quantitative variable that can take on an uncountable set of values
- D. A categorical variable in which the number of categories continues to increase over time
Correct answer: C
Explanation
A continuous variable is one that can assume an uncountable set of values within a given range, making option C the correct choice. Option A incorrectly suggests that continuous variables are always changing, while option B describes discrete variables, which can only take on countable values. Option D refers to categorical variables, which do not fit the definition of continuous variables.
