This course covers basic epidemiology principles, concepts, and procedures useful in the surveillance and investigation of health-related states or events. It is designed for federal, state, and local government health professionals and private sector health professionals who are responsible for disease surveillance or investigation.
Graphs and statistics. Frequency Histograms, Box Plots and Dot Plots. Teacher Centered Introduction. Overview of Lesson - activate students' prior knowledge - vocabulary To create a histogram, first complete a frequency table to show the number of values in intervals of equal size.
The dot plot as a representation of a distribution consists of group of data points plotted on a simple scale. Dot plots are used for continuous, quantitative, univariate data. Data points may be labelled if there are few of them. Dot plots are one of the simplest statistical plots, and are suitable for small to moderate sized data sets.
Guidelines for Plotting Frequency Distributions. The frequency distribution of events is the number of times each event occurred in an experiment or study. Frequency distributions can be displayed in a table, histogram, line graph, dot plot, or a pie chart, just to name a few.

How to enter data as a cumulative frequency table? Similar as frequency table, but instead f: type cf: in second line. For example: 10 20 30 40 50 60 70 80 cf: 5 13 20 32 60 80 90 100 The cumulative frequency is calculated by adding each frequency from a frequency distribution table to the sum of its predecessors.
