Other questions on the SAT may have graphs that are not related to or linked with functions. In these cases they may have a function with them but most of the time they will be based on just the information that is presented in the question.
TIP: Many data analysis questions test the ability to read the question carefully and notice the particular details. As with other sections of the SAT, it is important to read with comprehension to know what the test makers want for the correct answer.
A scatterplot will show data that deals with variables related to the same events. On the SAT they may ask to use the data presented. In these cases, it is simply a matter of using the information as would happen with other questions with charts. However, in these cases, each value in a column would relate to the same variable.
