Independent variable: the variable that is manipulated by the researched. The iv consists of the antecedent conditions that are manipulated by the researched prior to observing the dv. Assessing the effect of social comparison performance feedback on state anxiety levels among children high in performance trait anxiety . Hypothesis an a priori prediction about the outcome of a study. In experimental research, a hypothesis predicts how the manipulation of the iv will affect the dependent variable. Hypothses are the core of science and experiments. Kids were told they are either performing or underperforming relative to others. Q: what is the dependent variable/construct being measured? (ex.
