In numeric data summaries, which option correctly states an additional function included beyond COUNT, MEAN, and STD?

• A. MIN and MAX
• B. TOP and UNIQUE
• C. MEDIAN and MODE
• D. SUM and PRODUCT

Answer: (A)

When summarizing numeric data, you want to convey not just the center and spread but also the range of values. COUNT gives how many observations, MEAN gives the average, and STD shows variability around that average. The natural next piece is the extreme values: the smallest and largest observations, i.e., the minimum and maximum. Including these two bounds completes a simple, informative snapshot of the data, showing where the data sit on the scale and how wide the spread can be. Other options introduce metrics that aren’t as universally part of a basic descriptive summary—MEDIAN and MODE can be useful but aren’t as universally paired with COUNT, MEAN, and STD, and TOP/UNIQUE or SUM/PRODUCT aren’t standard additions to that particular trio.
