### Scatter Plots and Trends - YourTeacher.com - Math Help

For a complete lesson on scatter plots and trends, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that a scatter plot is a graph in which the data is plotted as points on a coordinate grid, and note that a "best-fit line" can be drawn to determine the trend in the data. If the x-values increase as the y-values increase, the scatter plot represents a positive correlation. If the x-values increase as the y-values decrease, the scatter plot represents a negative correlation. If the data is spread out so that it is not possible to draw a "best-fit line", there is no correlation. Students are then asked to create scatter plots using given data, and answer questions based on given scatter plots.
