    Question

    An investigation of personal injury (Y) in a moped accident involves measuring the speed of the moped (X) and whether or not a helmet was worn (M). It is investigated whether M is a mediator. One takes two steps: 1) regression with Y as dependent and X as independent variable. 2) regression with M as dependent and X as independent variable.

    If there are significant results in steps 1) and 2), what is the next step?


    1. FALSE: Regression with Y and M as independent variables and X as dependent.
    2. FALSE: Regression with X and Y as independent variables and M as dependent.
    3. TRUE: Regression with X and M as independent variables and Y as dependent.
    4. FALSE: Regression with Y as independent variable and X as dependent.
