                A researcher is measuring the heart rate of subjects as an index of anxiety. In this study, heart rate is
1) negatively correlated with anxiety
2) an independent variable
3) an operational definition of anxiety
4) a confounded variable
i think its number 3 or 4 is that right

    You said 3 or 4. It's clearly not 4, so what's your other considered choice?

    The heart rate typically <I>increases</I> with the anxiety level, so it can be used as an operational definition of anxiety. (It is one of the indicators used in the lie detector.)
