How do exploratory ad-hoc analyses differ from routine analysis?

Question

Options

• AThey involve querying known patterns without exploring further.
• BAd-hoc analyses deviate from established routines, exploring patterns and anomalies in data.
• CAd-hoc analyses focus on anomalies and established trends.
• DAd-hoc analyses rely heavily on predefined queries.

• A
  4% (2)
• B
  92% (46)
• C
  2% (1)
• D
  2% (1)

Explanation

Option B is correct because ad-hoc analyses are by definition unplanned, one-off investigations that deviate from established workflows - they're driven by curiosity or unexpected findings, exploring patterns and anomalies that weren't anticipated in advance.

Why the distractors fail:

• A describes the opposite of ad-hoc - querying known patterns without further exploration is what routine analysis does.
• C is partially right (anomalies, yes) but "established trends" contradicts the ad-hoc nature; routine analyses follow established trends.
• D is wrong because predefined queries are the hallmark of routine analysis; ad-hoc queries are constructed on the fly to answer novel questions.

Memory tip: Think of "ad-hoc" as Latin for "for this specific thing" - it's improvised, not scripted. Routine = script; ad-hoc = improv.
