In this experiment,the risk-taking propensity of 90 inner city drug users was measured using a repeated measures test called the Behavioral Analogue Risk Task (BART;Lejuez et al. ,2002).The higher the BART score,the higher the risk-taking propensity.Participants also filled out questionnaires so that their Psychopathic Personality Inventory (PPI)scores could be computed.PPI scores are used to detect psychopathic traits in a covert manner and are a common indicator of one's level of psychopathy.The main goal of the experiment was to examine the relationship between risk-taking (measured by BART)based on one's level of psychopathy (measured by PPI on a scale of 0-100),gender (1 for male and 2 for female),and heroin use (1 for heroin use and 0 for no heroin use).Below is a partial output of a multiple regression analysis. What is the response variable in this study?
A)Gender and Bart score
B)BART score
C)Gender and PPI
D)Gender,heroin,and PPI

The response variable in this study is the BART score, as it is the variable being measured as an indicator of risk-taking propensity. The other variables (gender, PPI score, and heroin use) are predictor variables being examined for their relationship with the BART scores.
