A company sets different prices for a particular DVD system in eight different regions of the country. The accompanying table shows the numbers of units sold and the corresponding prices (in dollars). Plot the data using a scatter plot with sales as the dependent variable and price as the independent variable. $$ \begin{array}{rrrrrrrrr} \hline \text { Sales } & 420 & 380 & 350 & 400 & 440 & 380 & 450 & 420 \\ \hline \text { Price } & 104 & 195 & 148 & 204 & 96 & 256 & 141 & 109 \\ \hline \end{array} $$

Key Concepts

Data Visualization

Data visualization is the graphical representation of information and data to help identify patterns, trends, and relationships. Techniques like scatter plots simplify complex data sets, allowing for easier interpretation and decision-making in analytical tasks.

Dependent Variable

The dependent variable is the outcome of interest in an analysis. It is plotted on the y-axis and its changes are examined in response to changes in the independent variable. This variable is measured to determine the effect of the independent variable.

Independent Variable

The independent variable is the variable that is manipulated or categorized in an analysis. In the context of a scatter plot, it is typically placed on the x-axis and is believed to be the cause or predictor, influencing the dependent variable.

Scatter Plot

A scatter plot is a type of data visualization that displays values for two quantitative variables as a set of points. Each point represents an observation and its coordinates are determined by the measurements of the two variables. This type of plot is particularly useful for identifying patterns, trends, or correlations between the variables.
