A scatter plot, or scattergraph, is a type of chart that displays values for two variables for a set of data. Each axis on the graph represents a variable. In today's free 7th grade math video on Scatter Plots, Edward Burger uses two variables as an example: hours of study and math scores. By plotting each point from the number set, you'll find most likely find more meaning in the scatter plot than the table of numbers. As with most graphs, by visualizing the data, a trend may become clearer.
Professor Edward Burger will help you learn not only how to create a scatter plot, but also how to read one. Learn how to determine when there is no correlation between the two variables and when there is a negative or positive correlation.
