Question

In yet another part of her research process, Blanca decides she needs to determine if the situation with acute care patient access for discharge planning is a constant one or if it varies widely. The tool she is using helps her assess the presence of unexplained variations by using upper and lower limits of variance. This tool is best called the:

A. Histogram

B. Stratification table

C. Pareto Chart

D. Control chart

Answer 1

The tool Blanca is using to assess the presence of unexplained variations is a Control chart.

Step-by-step explanation:

The tool she is using to assess the presence of unexplained variations by using upper and lower limits of variance is a Control chart.

A control chart is a statistical tool that helps determine if a process is in control or experiencing variations beyond the acceptable limits. It plots data points over time and includes upper and lower control limits that help identify whether the process is consistent or varying widely.

For example, in Blanca's case, she can use a control chart to monitor the acute care patient access for discharge planning and analyze if the process is consistent or exhibiting significant variations.
