Which action aids in performing a diagnostic analysis on historical data to identify reasons/causes of anomalies?

Question

Options

• ACollecting related data and demographics
• BFocusing on isolated data points
• CIgnoring statistical trends in historical data
• DAnalyzing data solely from the past month

• A
  89% (25)
• C
  7% (2)
• D
  4% (1)

Explanation

Collecting related data and demographics (A) is correct because diagnostic analysis requires broad contextual information - related data points and demographic factors help reveal why anomalies occurred, not just that they occurred. Identifying root causes demands a holistic view of interconnected variables, not a narrow slice.

B is wrong because focusing on isolated data points does the opposite - it strips away context, making it harder to spot patterns or correlations that explain anomalies. C is wrong because statistical trends in historical data are the primary tool for diagnosing anomalies; ignoring them makes root cause analysis impossible. D is wrong because limiting analysis to a single recent month may exclude the historical baseline needed to recognize what's actually anomalous.

Memory tip: Think of "diagnostic" like a doctor's diagnosis - a good doctor collects your full history and demographics, not just today's symptoms. Collecting related data = collecting the full patient chart.
