Answer:
The intensity of self-control
Step-by-step explanation:
A researcher argues that individuals with low self-control are more likely to commit crimes than individuals with high self-control. The independent variable in this proposition can be stated most clearly as the intensity of self-control.
The intensity of self-control will be the independent variable and tendency to commit crime or the number of crimes committed will likely be the dependent variable.
An independent variable is a variable whose variation does not depend on that of another one and intensity of self-control in the study is not dependent on another variable.
