This lesson will introduce scatter plots, how to read and interpret a scatter plot, and how to describe patterns of data trends. You will discover the types of association that may exist between two variables when comparing data. There is a positive association when x and y both increase. There is a negative association when y decreases as x increases. There may also be no association which communicates that the variables do not have a relationship.
