Run charts are an effective way to view changes over time. They are much easier to interpret visually
than a list of numbers or a static display of data such as a bar chart.
When designing the run chart, it is important to include: - ANSWER✔✔-Units of time on the X axis
The run chart should display units of time — whether it's days, weeks, or months — on the X axis. The Y
axis is where you plot the key variable you are measuring, which in this case is the rate of UTIs.
What is the minimum number of data points you should usually have to look for signs of improvement
on a run chart? - ANSWER✔✔-10
A run chart becomes more powerful as you add more data points because there will be more
opportunities to identify patterns. If you're looking for signs of improvement, usually you need at least
10 data points.
Which of the following is a problem with static data? - ANSWER✔✔-It doesn't adequately portray
variation.
