What does the rare command do?

Question

Options

• AReturns the least common field values of a given field in the results.
• BReturns the most common field values of a given field in the results.
• CReturns the top 10 field values of a given field in the results.
• DReturns the lowest 10 field values of a given field in the results.

• A
  77% (23)
• B
  13% (4)
• C
  3% (1)
• D
  7% (2)

Explanation

Option A is correct because the rare command returns the least common field values - it is the opposite of the top command, which returns the most frequent values. Option B describes top, not rare, making it a common mix-up trap. Options C and D both reference "top 10" or "lowest 10," which conflate the concept of frequency ranking with value magnitude - rare deals with statistical frequency (how often a value appears), not numerical size. A helpful memory tip: think of rare as literally meaning "uncommon" - just as rare items are hard to find, the rare command surfaces field values that appear least often in your dataset.
