SCATTER CHARTS

Background

Similar to Line Graphs, Scatter Charts are a simple visualization for data points to be plotted without drawn lines connecting them. They are often useful for comparing each point separately or groups of points from different events. Characteristics and behaviors of these data sets may be determined by observing Scatter Charts.

Description

Go to the SOCR Charts and select Line Charts from the items located on the left, then select the demonstration for Scatter Charts:

The image above is a demonstration of a simple Scatter Chart. Note that below the graph shows the statistical values for each event.

Data Type and Format

By clicking Data between the Graph and Mapping button, it allows users to input or vary the values of the data set. There is one type of variable which is quantitative or numerical that are listed to the corresponding event:

Applications

One of the most persuasive elements when proposing data and literature to others is a well-designed chart presentation.

For example, students in labs may want to present their table of values in a graph. By using the Scatter Chart, every unique data value will be equally represented in the Scatter Chart.

Suppose that researchers are interested in the cholesterol level in a group of adults. By plotting every data set, all of the values are equally represented in the Scatter Chart.
