Answer:
A title.
Step-by-step explanation:
The thing missing here is not regarding the calculations, because Suzette even draw the line that explain the relation between the two variables, which also are included there. However, Suzette didn't include the title of the graph, so basically, we don't know to which problem belongs that graph. This is an important issue, because in lab report, we tend to have a lot of information, and if it's not identified, it's completely useful.
