QI 103 Lesson 2: How to Use Data for Improvement
During the "study" phase of PDSA (Plan-Do-Study-Act), you'll try to understand what the data you're collecting is telling you. But a long list of numbers won't tell you much. To provide a clearer picture of whether your changes are leading to improvement, you need to display your data in a dynamic manner. In this lesson, you’ll learn the value of displaying your data over time, on a run chart. We'll also show you how to break the data down into subsets, according to specific variables, to bring out additional learning and opportunities for improvement.
Estimated Time of Completion: 25 minutes
