If you set up an experiment with two different independent variables, then the results would be_____.


A.inconclusive; you would not know which of the two variables caused the change

B.definitive; the results would be more accurate if you change two variables at a time

C.conclusive; showing a strong correlation between dependent and independent variables

D.somewhat conclusive; you know the change resulted from one of the variables

I think the correct answer from the choices listed above is option A. If you set up an experiment with two different independent variables, then the results would be inconclusive; you would not know which of the two variables caused the change. Hope this helps.

Answer: A) Inconclusive; you would not know which of the two variables caused the change.


Justification:


When you set up an experiment, you must make sure that you control the variables such that only one independent variable changes at a time, while all the remainder conditions (the other independent variables) are controlled (fixed).


By observing (measuring) the dependent variable, while only one independent variable changes you can understand how such dependent variable is explained (determines) by the dependent variable, leading to a conclusion.


Conversely, if two or more independent variables change at a time , then there is no way you can tell how the output (dependent variable) is related with one or other of the changes of the indipendent variables. You wolud not be able to discriminate (distinguish) the effect of one or other variable, making the experiment inconclusive
