Which port in the StatisticsCalculator is used to view cumulative results?

• A. Cumulative port
• B. Main output port
• C. Result port
• D. Summary port

Answer: (A)

Statistics calculators can emit multiple outputs, and to see how statistics build up as data flows through, you use the cumulative port. This port streams running statistics—counts, sums, means, mins, maxes, and any other tracked metrics—as each feature is processed, so you can watch the values evolve over time. The main output port passes the processed features onward but doesn’t focus on the statistics themselves. The result port provides the computed statistics for the current state, not the ongoing accumulation. The summary port offers a final, aggregate snapshot after processing completes. So, for observing ongoing, incremental results, the cumulative port is the one designed for that purpose.
