Which data visualization illustrates the impact of process change to staff related to patient experience...

This question aligns with Measurement and Analysis , particularly the use of data visualization to demonstrate improvement over time. Run charts (Option C) are the most appropriate tool because they display data points in chronological order , allowing staff to see trends, shifts, and the direct impact of process changes over time. CPXP principles emphasize that run charts are especially effective in quality improvement because they make it easier to identify whether changes lead to sustained improvement. In contrast, bar graphs (A) compare categories, pie charts (B) show proportions, and box-and-whisker plots (D) display distribution and variability—none of which clearly show change over time. Run charts help engage staff by visually connecting their actions to outcomes, reinforcing accountability and supporting continuous improvement in patient experience.
