Question

which of the following is the best use for a double bar graph? * displaying the temperature change in one city during a week; showing the parts of a plant; showing the population growth of one city over time; comparing the test scores of boys and girls in different subjects

Explanation:

A double - bar graph is used to compare two sets of data. Comparing the test scores of boys and girls in different subjects involves two sets of data (boys' scores and girls' scores) for different categories (subjects), which is an ideal situation for a double - bar graph. Displaying temperature change is better with a line graph, showing parts of a plant is better with a diagram, and showing population growth over time is better with a line graph or an area graph.

Comparing the test scores of boys and girls in different subjects
