Explanation:

In a graph, the independent variable is typically the one that is manipulated or is the cause, and it's usually plotted on the x - axis. Here, the x - axis is labeled "Years" with values from 2013 to 2025. The other variables (like number of injuries for different body parts) depend on the year, so the independent variable is Years.

Answer:

Years
