Which of the following is the correct definition of Data Values for a graph?

The correct definition of Data Values for a graph refers specifically to the displayed frequencies or relative frequencies summarizing the data. These values represent quantitative information that the graph is designed to convey to the viewer. In other words, data values are the numerical representations that showcase the distribution, trends, or proportions of the data being visualized.

When creating a graph, it is essential to accurately present these data values because they provide meaningful insights into the subject matter being analyzed. Whether it is in a bar graph, line graph, or pie chart, the data values are the essence of what the graph communicates. They help the reader understand the magnitude and relationships within the data set.

The other options do not define Data Values accurately. The title of the Y axis generally denotes what variable is being measured, while the X axis title indicates the variable represented along that axis. Starting a graph scale at zero is a visual formatting guideline that can enhance clarity but does not pertain specifically to data values. Thus, focusing on the concept of displayed frequencies or relative frequencies is correct in defining what Data Values represent in the context of a graph.
