Which statement best describes a check sheet's purpose?

• A. Flowchart maps sequence of steps and decisions.
• B. Check sheet is used to collect data in real time in a structured format for analysis.
• C. Ishikawa diagram shows distribution shapes.
• D. P-chart displays the proportion defective.

Answer: (B)

A check sheet is a data collection tool designed to capture observations as they occur, in a standardized, structured format so the data can be analyzed later. This setup makes it easy to tally frequencies, identify patterns, and support subsequent analysis (like histograms or Pareto charts) because every data point is recorded in the same way at the source. It’s not about mapping steps in a process—that’s what a flowchart does. It isn’t about exploring potential causes with relationships and categories—that’s an Ishikawa (fishbone) diagram. And it isn’t about showing the proportion of defectives over time—that’s a P-chart. The check sheet’s purpose is specifically to collect data in a consistent format for analysis.
