Which quality tool records variables and attributes during inspection?

• A. Scatter Diagram
• B. Fishbone Diagram
• C. Checksheets
• D. Pareto Chart

Answer: (C)

Recording variables and attributes during inspection is addressed by checksheets. A checksheet is a simple data collection form used to capture data as observations occur, often with tally marks or fields for counts, measurements, or yes/no attributes. It ensures data are collected consistently, allowing you to tally defects by type, track occurrences over time, or record pass/fail results. This raw data then supports later analysis and decision-making. The other tools have different purposes: a scatter diagram maps the relationship between two numerical variables to explore correlation; a fishbone (Ishikawa) diagram helps identify root causes; a Pareto chart prioritizes issues by frequency or impact to focus improvement efforts.
