[C, R, T, V]
| (a) |
Compare graphs in which different correspondences are used and explain why the correspondence may have been used. |
| (b) |
Compare graphs in which the same data have been displayed using a one-to-one and a many-to-one correspondence, and explain how they are the same and different. |
| (c) |
Explain why a many-to-one correspondence is sometimes used rather than a one-to-one correspondence. |
| (d) |
Find examples of graphs in which a many-to-one correspondence is used in print and electronic media, such as newspapers, magazines, and the Internet, and describe the correspondence used. |
| (e) |
Select many-to-one correspondence for displaying a set of data in a graph and justify the choice. |
| (f) |
Create and label (with categories, title, and legend) a pictograph to display a set of data using a many-to-one correspondence, and justify the choice of correspondence used. |
| (g) |
Create and label (with axes and title) a bar graph to display a set of data using a many-to-one correspondence, and justify the choice of correspondence used. |
| (h) |
Answer a question using a graph in which data are displayed using a many-to-one correspondence. |
