Visualizing Biostatistics with Histograms, Curve Graphs, and Pie Charts
Explore the use of histograms to display frequency information, curve graphs to illustrate trends, and pie charts for percentage distributions in biostatistics. Learn how to construct and interpret these graphical representations for data analysis in the medical and health technologies laboratory.

HISTOGRAMS HISTOGRAMS Frequency information for interval-level and ratio-level data can be displayed in a histogram, which is a graphic display similar to a bar graph. In a histogram, however, the bars touch one another because adjacent values are not distinct categories, but rather contiguous scores on an ordered dimension.
EXAMPLE 8 Construct A Histogram Graph For The Data In Example (Heart Rate Data) And Display The Normal Curve.
The Curve Graphs it is used to clarify the general trend of one or more phenomena during a specific period. 1. Display the number of males data from previous Example using a simple curve graph. 2. Display the data from Example 6 using a multiple curve graph.
The Pie Charts The pie chart (sometimes called a circle graph) is a circle divided into pie-shaped wedges corresponding to the percentages The angle of a pie = the frequency percentage of the pie 360. For example, the angle of pie for married patients = 40/100 360 = 144.
The Pie Charts Cumulative Percent Frequency Percent Valid Percent Valid Married 12 40.0 40.0 40.0 Single 6 20.0 20.0 60.0 Divorced 8 26.7 26.7 86.7 Widowed Total 4 13.3 100.0 13.3 100.0 100.0 30
