A variable is something that can vary or change. What are the variables in this statement? The time it takes to run a 10 km race depends on the amount of training the runner does. Click to check your answers

The time it takes to run a 10 km race depends on the amount of training the runner does. The manipulated variable is the amount of training. The responding variable is the time it takes to run a 10 km race. It is not enough to say just time or training – you must describe the MV and tell how the RV is measured. Click for another question

What are the variables in this statement? The temperature of water will be different when measured at different depths in a lake. Click to check your answers

The temperature of water will be different when measured at different depths in a lake. The manipulated variable is the depth of the lake. The responding variable is the temperature of the water. Click for another question

What are the variables in this statement? The more water a plant gets, the taller it will grow. Click to check your answers

The more water a plant gets, the taller it will grow. The manipulated variable is the amount of water. The responding variable is the height of the grass. Click for another question
