Answer-first summary for fast verification
Answer: A branch of statistics that uses summary statistics to quantitatively describe and summarize data.
Option A correctly defines descriptive statistics as using summary statistics (like mean, median, mode, standard deviation) to quantitatively describe and summarize data, focusing on understanding data features without making inferences. This aligns with the community consensus (100% selected A) and the detailed reasoning provided, which emphasizes that descriptive statistics summarize data characteristics without inferring properties of an underlying distribution. Option B describes inferential statistics, not descriptive. Option C and E refer to types of variables (discrete and continuous, respectively), not branches of statistics. Option D is incorrect because descriptive statistics use quantitative, not categorical, description.
