For what purpose is a scatter plot used?

A scatter plot is a valuable tool for visualizing the relationship between two continuous variables. By plotting individual data points on a Cartesian plane, where each axis represents one of the variables, the scatter plot allows analysts to observe patterns, correlations, and trends that may exist between the two variables.

The use of a scatter plot highlights various aspects such as the strength and direction of the relationship. For example, if the points represent a positive correlation, they will generally slope upwards from left to right, while a negative correlation will show a downward slope. Additionally, researchers can identify outliers or clusters of data points, which can provide insights into the data's characteristics.

Utilizing scatter plots is crucial when analyzing relationships, as they can indicate potentially significant associations that inform further analysis or decision-making.
