Quizplus · Accepted Answer

A scatter plot can detect all of the relationships listed in the answer choices. A positive linear relationship can be observed when the data points form a pattern that increases in a linear fashion from left to right. A negative linear relationship can be observed when the data points form a pattern that decreases in a linear fashion from left to right. A curvilinear relationship can be observed when the data points form a curved pattern, such as a U-shape or a parabolic shape. The presence of an outlier can be identified as a data point that is significantly different from the other data points in the scatter plot.
