Which of the following can be identified using a run chart?

Relationships between variables are typically identified using a scatter diagram, not a run chart.

Causes of defects are typically identified through root cause analysis tools like fishbone diagrams or Pareto charts, though a run chart can show when defects occur.

While a run chart displays data from a sample, it identifies patterns or trends within that data, not the 'sample' itself as an output.

A run chart is a line graph that plots data points in chronological order, allowing project teams to visually identify trends, shifts, cycles, or other non-random patterns in a process over time. This helps in understanding process behavior and stability.
