Scatterplots are used to investigate the relationship between __ numerical data.

Understanding Scatterplots

1. Definition: A scatterplot is a type of graph that uses dots to represent the values obtained for two different variables: one plotted along the x-axis and the other plotted along the y-axis.

2. Purpose: Scatterplots are primarily used to explore the relationship between two numerical data sets. By plotting one numerical variable against another, we can visualize how one variable relates to the other, which helps in identifying trends, patterns, or correlations.

3. Conclusion: Therefore, scatterplots are used to investigate the relationship between two numerical data sets, allowing researchers and analysts to determine forms of relationships (positive, negative, or none) and the strength of those relationships.

In summary, scatterplots are effective tools for examining how the change in one numerical variable affects another, making them invaluable in fields such as statistics, economics, biology, and many others where data analysis is crucial.
