What would be my independent variable for this project?

If I were to find the ratio of native and alien plants species in my garden and compare that with the ratio of the native and alien plants in a piece of land that has been undisturbed by humans, what would be my independent variable? Do I even have one? If not, then what could I change to create that variable. |||HI i am not a statistician or research scientist but I am an environmentalist and glad you are stuyding native plants.





This is from wikipedia


Dependent variables and independent variables refer to values that change in relationship to each other. The dependent variables are those that are observed to change in response to the independent variables. The independent variables are those that are deliberately manipulated to invoke a change in the dependent variables





If i interpret it correctly, this means that your dependent variable are the population numbers. the independent variables are the location of the count.|||An independent variable would be weather.


Another, the type of soil base.


Another the specie.|||Independent variable is the one you change on purpose. So the species of plant.


:)|||You have two data points, your garden %26amp; undisturbed land. A variable would be the distance from undisturbed land from your garden, but that requires more data points|||garden vs. land undisturbed


this is independent variable because it is the only thing that has been changed in the experiment.


ratio of native and alien plant species is dependent, while the disturbed/undisturbed land is independent|||the variable is what differs between your two sources- in this case the variable is most likely the effect of humans- in your garden you may have weeded certain plants out, or trod on some, or some animals found in your area have interfered with them in some way. the undisturbed land will have none of these things. the variable, therefore, is human influence.





good luck|||there is no independent variable. the independent variable is something that you change. so to have an independent variable you have to change something.
