Question: 1 / 400

What is a scatter plot primarily used for?

To compare categorical data

To display the distribution of a single variable

To display the relationship between two quantitative variables

A scatter plot is primarily used to display the relationship between two quantitative variables. This type of chart allows you to visually assess how one variable may be affected by or correlate with another. Each point on the scatter plot represents an observation in the data, with one variable plotted along the x-axis and the other along the y-axis. By analyzing the pattern of the plotted points, you can identify trends, correlations, or potential relationships between the two variables.

For instance, if you were studying the relationship between hours studied and exam scores, a scatter plot would help you see whether an increase in study hours correlates with higher scores. If the points cluster in a way that suggests a trend (e.g., moving upwards from left to right), this would indicate a positive correlation, while points that are spread out with no clear trend would suggest little to no correlation.

This visual representation is particularly powerful in statistics and data analysis, allowing for the identification of patterns that might not be apparent from just looking at the raw data.
