Scatter Plot and Line of Best Fit

Videos, worksheets, stories and songs to help Grade 8 students learn about scatter Plots, Line of Best Fit and Correlation.

Scatter Plot
In this video you will 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.
