Graphs: Tool of Organization



Graphs


Tool of Organization





Objective 1


Graphs are a visual way to express information regarding the relationship between two or more factors. Looking at a long page of numbers can be not only boring, but intimidating. After a while, the numbers blur together and misinterpretation of the information can occur. A graph can quickly convey such information as gross profit or loss, most profitable months, where most of the budget is used, and so on.




In this chapter, we use different types of graphs and charts. You will learn how to create charts to reflect specific information. Depending on the availability of a computer, many of these exercises can be completed with the use of an electronic spreadsheet. Typically, working from an electronic worksheet will allow you to set up data sheets and create a graph. Once your graph is created, you can copy it to a word-processing document for reports.



Objective 2


Graphs


A graph is a picture or diagram that reflects a relationship of two or more data sets. All graphs have a vertical axis and a horizontal axis. These scales are divided into increments that represent a ratio to the exact quantity. Once the variables for the axis have been established, the information is plotted. Line graphs are one of the most common types of graphs for plotting points from one or more data sets. Line graphs are commonly used to plot information that may have an increased chance for change. Once the information is plotted, a line is drawn from point to point. This gives a visual representation of the changes that occur in the data set or sets. If you are using more than one data set, each data set will be assigned a specific color to represent the information.


Graphs can be used to give a general description or illustration of the data set, trends, or the high and lows of the information. To get actual information from a line graph, however, it helps to have the actual data set available for reference.


Example:


Number of people seen at Brightwood Hospital per year


























Year Number of People Seen
1995 15,000
1996 22,000
1997 25,000
1998 23,500
1999 24,500
2000 26,500


Here is the same information plotted as a line graph.

Graphs can be used to extract information quickly. Look at the line graph regarding the number of people seen at Brightwood Hospital per year (above) and answer the following questions:




Objective 2






Use the above strategies to plot the information from the following data set:














































Year Patients Seen in ER Patients Seen in Outpatient Surgery Patients Seen as Inpatients
2000 25,000 15,000 18,500
2001 25,500 16,500 20,000
2002 27,500 16,000 21,500
2003 26,500 15,500 22,000
2004 28,000 17,000 23,500
2005 27,500 18,000 23,000
2006 25,000 16,000 21,500

Here is what the line graph would look like:

1. Use graph paper or a computer to plot the following data to create a line graph.




























Year Live Infants Born
2000 550
2001 475
2002 575
2003 600
2004 525
2005 500
2006 625

2. The following data set represents the number of patients seen in a physician’s office per day for one month.






















Monday 32
Tuesday 26
Wednesday 22
Thursday 28
Friday 32
Saturday 17


3. The following data set represents the number of males and females ages 12 to 18 seen in the laboratory in the first half of the year. Create a chart to represent the data sets.




























January 150 males 175 females
February 112 males 145 females
March 125 males 115 females
April 100 males 120 females
May 90 males 85 females
June 75 males 90 females

4. Answer the following questions based on the graph below.

Objective 3


Measurement graphs


Many facilities have standardized graphic sheets. These sheets can be used to record vital signs (vital sign graphs) and fluid intake and output (intake and output graphs). Because necessary information has been recorded in one place on the graphic sheets, a reviewer can look at trends over a specified period.


The purpose of this section is introduce you to the use of different measurement graphs in the health care setting. Become familiar with the organization of the measurement graphs and how they can be used; in this section, you will be transferring information to the correct section of a graph. As you continue on your educational pathway in health care, you will receive detailed instruction on the use and values of measurement graphs.



Vital Sign Graphs


Look at Figure 12-1. Which part of the chart is considered the vital sign graphic sheet? By viewing the graphic sheet, you can easily tell when the patient’s temperature was above normal (98.6° F).
