Scatterplots display the relationship between two variables using points on a Cartesian plane. The points represent individual data points, and their arrangement can indicate various types of relationships:
-
Linear Relationship: If the points roughly form a straight line (whether upward or downward), it suggests a linear relationship between the variables.
-
Non-linear Relationship: If the points follow a curved pattern, it indicates a non-linear relationship.
-
No Relationship: If the points are randomly scattered with no discernible pattern, it suggests that there may be no relationship between the two variables.
In summary, scatterplots are not inherently in a straight line; their structure is determined by the nature of the relationship between the variables being plotted.
