A scatter diagram (or scatter plot) can be used to describe the relationship between two numerical (quantitative) variables.

Here's why:

1. Scatter Diagram: This type of graph displays values for typically two variables for a set of data. The data are displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis. This helps in visualizing any potential correlation or relationship between two numerical variables.

2. Bar Chart: This is typically used for comparing the quantity, frequency, or other measure for different categories or groups.

3. Histogram: This is used for showing the underlying frequency distribution of a set of continuous or discrete numerical data.

4. Pie Chart: This is used to show
