Attitudes toward recycled products Some people believe recycled products are lower in quality than other products, a fact that makes recycling less practical. Here are data on attitudes toward coffee filters made of recycled paper from a random sample of adults: $^{21}$ $$ \begin{array}{lcc} {\text { Recycled coffee filter status }} \\ \text { Quality rating } & \text { Buyers } & \text { Nonbuyers } \\ \text { Higher } & 20 & 29 \\ \text { Same } & 7 & 25 \\ \text { Lower } & 9 & 43 \\ \hline \end{array} $$ Make a well-labeled bar graph that compares buyers' and nonbuyers' opinions about recycled filters. Describe what you see.

Key Concepts

Categorical Data

Categorical data consists of values that represent distinct groups or categories, such as opinions, types, or classifications. This type of data is best visualized with bar graphs because the individual categories can be directly compared based on their counts or frequencies.

Comparative Analysis

Comparative analysis involves evaluating and contrasting two or more groups across the same categories. In the context of data visualization, this often means placing the categories side by side to observe differences in trends or patterns, which helps in understanding how attitudes or behaviors vary between groups.

Bar Graph

A bar graph is a chart that uses rectangular bars to represent the frequency or magnitude of categories. Each bar's length or height is proportional to the value it represents, making it easy to compare different groups or categories at a glance.

Graph Labeling

Graph labeling is the process of providing clear and informative titles, axis labels, legends, and other annotations in a graph. Proper labeling is essential for interpreting the data correctly and making the graph self-explanatory, ensuring that the viewer understands what each element of the graph represents.
