How do I know if my quantitative message is a Time Series?
A quick and easy way to determine if your message is a time series is to write down in a short sentence describing what you need to convey to your audience. For example:
- I want to show how our average daily census has increased since we opened a new surgical floor.
- I want to show the trend in emergency room use from midnight to 7:00am.
- I want to show the decrease in our rate of fall with injuries on medical floors.
- I want to show how our oncology services have grown since we added staff.
- I need to monitor the change in the patient’s blood pressure rate.
Did you use any of the following words* in your sentence?
- Change
- Rise
- Increase
- Fluctuate
- Grow
- Decline
- Decrease
- Trend
If you did then you should most likely use one of the following graphs to display your data:
- Vertical Bar Graph
- Line Graph
- Vertical Dot Plot
- Multiple Strip Plot
- Vertical Box Plot
* These words, with the exception of “trend,” were suggested by Gene Zelazny (2001) Say It with Charts, Fourth Edition. New York: McGraw Hill. The word “trend” is from Stephen Few’s (2004) Show Me the Numbers, First Edition, California: Analytics Press.
