Question

why are graphs helpful for displaying data?
a. they are the only way to display data.
b. they help you identify patterns in the data.
c. they do not use numerical information.
d. they are easier to make than tables.

Explanation:

Graphs are visual representations. They can show trends, relationships, and distributions of data more clearly than raw data. For example, a line graph can show how a value changes over time, making it easy to spot patterns like growth or decline. Option A is incorrect as there are other ways to display data (e.g., tables). Option C is wrong because graphs often use numerical information (e.g., axes with numbers). Option D is not a valid general reason; the ease of making depends on the type of graph and table and is not the main advantage.

Answer:

B. They help you identify patterns in the data.
