Data is collected and analyzed in terms of which two aspects?

• A. Sampling interval and test duration
• B. Pressure and temperature
• C. Volume and velocity
• D. Time and rate

Answer: (A)

For data collection and analysis in tank tightness testing, the two aspects are how often you collect data and how long you observe. The sampling interval is the time between measurements, which sets your data’s temporal resolution and how well you can detect changes or leaks over time. The test duration is the total period you monitor the system, defining the window in which you can observe leakage behavior and determine if a leak is present. Other options refer to the physical quantities you might measure (like pressure and temperature) or derived ideas, but they don’t describe the two fundamental design choices that shape how data is gathered and analyzed.
