I need to identify the dependent variable, the independent variable, and the number if levels of independent variables in the following study:

Becca had students in a statistics class rate a resume, telling them that the person had applied for a position that included teaching statistics at their college. The students rated the resume on a scale of 1 (not qualified) to 10 (extremely qualified). All of the students received identical resumes, except that the candidate's first name was Jane on half of the resumes and John on the other half.
