If you are designing an experiment to investigate how different kinds of wheels accelerate down a ramp, which is the dependent variable?
|
|
type of wheel
|
|
|
steepness of the ramp
|
|
|
acceleration of the wheel
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Explanation: If Gloria is wanting to test how different kinds of wheels accelerate down a ramp, then she is manipulating the type of wheel to measure a change in the acceleration of the wheel. The acceleration (measured value) is thus the dependent variable since it depends on what type of wheel you roll down the ramp.
Detailed explanation-2: -Independent. An independent variable is the variable for which quantities are manipulated (selected or changed) by the experimenter, and assumed to have a direct effect on the dependent variable. Independent variables are plotted on the horizontal axis of graphs.
