If you checked Advanced Output Cumulative Results in the StatisticsCalculator, which statement is correct?

• A. Inspecting the Cumulative port results in an error in the Translation Log.
• B. AverageParkArea in the Cumulative port is updated for each feature processed, meaning that only the last feature processed in each neighborhood will actually be correct.
• C. The Cumulative port is not compatible with the Process at End (Blocking) Group By mode.
• D. The Cumulative port is not affected by Group By.

Answer: (B)

Advanced Output Cumulative Results shows running statistics as features flow through the StatisticsCalculator. Because the Cumulative port updates with each feature processed, the AverageParkArea you see is a running value, not a final, neighborhood-wide result. When you’re using Group By with Process at End (Blocking), each neighborhood is treated as a block, and the final aggregated values are only delivered after the block completes. That means the intermediate updates reflect partial accumulation, and the final, correct average for a neighborhood appears on the last feature processed in that neighborhood. So the key point is that the Cumulative port updates per feature, and only the last feature in each neighborhood yields the final correct value. The other statements don’t align with how cumulative results behave in this setup, and the port does respond to Group By by resetting as groups change, rather than being unaffected.
