Final answer:
A scatterplot shows the relationship between two variables, with one variable on the x-axis and the other on the y-axis. It is a true statement.
Step-by-step explanation:
The answer to the student's question is true. A scatterplot does indeed graphically show the relationship between two variables. This type of graph displays points that represent the values of two different variables: one measured on the x-axis, which is often the independent variable, and the other on the y-axis, typically the dependent variable. Each point on the scatterplot corresponds to one observation in the data set.
In some cases, a line graph may be more effective, especially for illustrating relationships between variables that change together over time, such as a time series showing unemployment rates. However, the uniqueness of a scatterplot is that it can quickly provide a visual indication of any correlation between the variables being studied, whether it is a positive or negative relationship, or if no clear relationship exists at all.
