Analysis of this chart shows which of the following?

Comprehensive and Detailed Explanation From Exact Extract:

In the Health Data Analytics domain, control charts are used to distinguish between common cause variation (normal system fluctuation) and special cause variation (abnormal variation requiring investigation).

In the chart shown, several points toward the end of the series approach or exceed the upper control limit (UCL) and display an upward trend beyond what would be expected due to random variation.

This pattern indicates the process is out of control, suggesting a special cause of variation such as a change in practice, infection control failure, or procedural deviation.

Therefore, the correct interpretation is that evaluation is needed to identify and correct the cause of this special variation.
