Question

choosing the right graph for one variable
identify why a bar graph would be more suitable than a circle graph for comparing the population of ten different cities.

1. it displays continuous data more effectively.
2. it allows for easier comparison between cities.
3. it is better for showing parts of a whole.
4. it can show changes over time more clearly.

Explanation:

Bar graphs are useful for comparing discrete data (like populations of different cities). Circle graphs (pie charts) are better for showing parts of a whole. Line graphs are better for showing changes over time. Continuous data is better shown with histograms or line graphs (not bar graphs). So the key is that bar graphs allow for easier comparison between distinct categories (cities in this case).

Answer:

1. It allows for easier comparison between cities.
