• BConduct a trend analysis and use a scatter chart.

Common mistakes.

• B. Conducting a trend analysis using a scatter chart is a more focused type of analysis typically performed after the initial exploration to examine relationships or changes over time.
• C. Link analysis and illustrating connection points is a specialized analytical technique used for understanding relationships within network data, not a general first step for all quick analyses.
• D. Conducting an initial analysis using a Pareto chart is specific to identifying and prioritizing factors contributing to a problem, which is a subsequent step after understanding the data's fundamental properties.
