If you change more than one variable at a time, you will not be able to tell which variable is responsible for what change. Scientists need to know exactly which variable caused the observed experimental results.
it is important to only have one variable in an experiment so you dont mix them up with other variables. such as different elements.
Because if you change more than one thing at a time and the outcome of the experiment is altered, then you won't know which changed variable caused the new outcome.
If you use multiple variables then you could not be fully sure which variable affected your final product in an experiment. It will also affect your data and conclusion.
Well, if you have more than one, how would you ever figure out which one was the one causing the results? If you only have one, you can tell how it affects the results immediately.
It is important to only change one variable at a time when doing an experiment, because if you change more than one, there will be uncertainty as to which one affected the result.
A variable is an element in an experiment that you control. There should only be one variable in an experiment or the results will not be accurate.
because in certain experiments you need an accurate independent variable so your conulsion could be accurate
Actually, you have two - dependent and independent. But, you only have one variable because otherwise the answer wouldn't be accurate if you had more than one variable.
What is a variable in a experiment
its important to have a manipulative variable so you have at least one variable that will reapond to what you do to it
Controlled Experiment :Pcontrolled experiment.
It is important to only change one variable at a time when doing an experiment, because if you change more than one, there will be uncertainty as to which one affected the result.
controlled experiment
Because if you change more than one variable at a time, you can't tell which is affecting the results.
a controlled experiment
If you change more that one variable in an experiment, then when the result occurs, you won't know which variable caused the change.
Controlled experiment
Controlled Experiment :Pcontrolled experiment.
It is called a controlled experiment.
A variable is an element in an experiment that you control. There should only be one variable in an experiment or the results will not be accurate.
If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference.
