Help please! what is the item that is the manipulated variable and what is going to be the responding Variable?
The manipulated variable is the part in a science experiment that you control. The responding variable is the part that you expect to change as a result of changing the manipulated variable. An example is if you cooled down some water and then measured how much space the water takes up. The temperature of the water is what you control, the manipulated variable. How much space it takes up (the volume) is what changes as a result of the change in the manipulated variable, and is called the responding variable because it responds to those changes in the first variable. Now, in the case of water, when you cool it down enough, it freezes. When it freezes, it expands, so it takes up more space. When you decrease the manipulated variable (the temperature of water) enough for it to freeze, you increase the the responding variable (the volume of water).
