A bar graph titled 'Statistical Analysis of Performance Metrics (Mean Differences)' compares three categories: Productivity, Defect Rate, and Machine Downtime. The x-axis represents the categories, and the y-axis represents the mean difference. There are three vertical bars, each representing a different category. The Productivity bar is blue and shows a positive mean difference of 13 units per hour. The Defect Rate bar is orange and shows a negative mean difference of 3.3 percentage points. The Machine Downtime bar is green and shows a negative mean difference of 28 hours per month. The graph indicates that productivity has increased, while defect rate and machine downtime have decreased. All values are approximated.Statistical analysis of performance metrics.
