What is the dependent and independent variable of this experiment?

Im doing an experiement on Fitness and Heart rate. Here is my question/hypothesis:



Does moderate excersize increase heart rate, if so, by how much? What is the dependent and independent variable?



(Thanks Emma)What is the dependent and independent variable of this experiment?
The independent variable is the variable that is being manipulated or changed.



The dependent variable is the thing you are measuring to see if the independent variable has had an effect on it.



So here you are measuring heart rate, and you want to know if exercise has an effect on heart rate, you want to know if the heart rate is "dependable" on exercise. So your independent variable is exercise. And the dependent variable is heart rate. Hope this helps!
The way to think about a question like this is "what is the cause; what is the resultant effect?"



The 'cause' is the 'independent variable', since this is what brings about the 'effect'. You can choose any value you like for the independent variable; the dependent variable simply 'does what it is told'! [Compare to a dependent child and its parent. ;-) ]



So you can see that the 'effect' is the dependent variable, since it depends on the 'cause' - the independent variable - to determine its value.



This concept of 'cause %26amp; effect' is at the heart of mathematics.



Glad to help.What is the dependent and independent variable of this experiment?
Independent: moderate exercise

Dependent: heart rate



a good way of identifying the variables is to just remember that the first variable in your problem is the independent variable and the second variable is the dependent.What is the dependent and independent variable of this experiment?
heart rate = dependent variable since it will increase or slow down based on amount of exercise



exercise = independent variable this will affect your heart rate
