Variables (R11) 9/6 What is a variable? 2) What are the three types of variables? 3) How can you tell the difference between variables? A variable is something that changes 2) Independent (IV) – I CHANGE Dependent (DV) – changes because of the IV Control (constant)- doesn’t change. You keep this the same so you only are changing 1 thing (IV) 3) The effect of IV on DV I change the IV to do my experiment. The DV is kind of like my results. Ex) The effect of soda brand on taste preference. SODA brand- IV, I CHANGE Taste preference – DV, depends on brand of soda
