-
1. All bars are the same width and go the same way either horizontally or vertically.
-
2. On the number line side, all units are the same width and each unit represents the same quantity.
-
3. If possible, begin number scale with zero and keep numbers unbroken. If not, indicate that the numbers are not consecutive from zero.
-
4. Arrangement of items to be compared may be done however seems best for the purpose: smallest to largest, largest to smallest, alphabetically, etc.
-
5. Graph has a title that can be understood and sides that are clearly labeled.
-
6. Is it easy to read?
-
7. Is it neat and attractive?
-
8. Do I need to credit source for the data?
