one limitation is a very small data set (it's hard to tell if the result is going to be different next time). Which brings up the subject of variability - are the initial conditions always the same (will my beaker be a little dirty or contaminated next time, will my lab partner click the stopwatch at exactly the same time, will I be distracted at the end of the experiment and miss an important detail...).
A good experiment is repeatable, a bad one gets different results each time.

What is an experiment in which only one factor is allowed to vary?
A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.
What dose controlled experiment mean?
this is an experiment that only one varible is manipulated at a time
Why is it imporatant to change systematically only one variable at a time when doing the 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.
What type of experiment does only one variable change at a time while all the other variables are kept unchanged?
A controlled experiment
How many variables are tested in a controlled experiment and why?
It depends on the experiment. Normally only one is tested at a time because they can affect the experiment. Variables are tested in a controlled experiment to see whether they affect the outcome and also how.
What are limitations in plant expirament?
Limitations in plant experiment entail the lack of one or all of the following: light, water, temperature and nutrients
Who conducted the classic experiment addressing the power of peer pressure that included six stooges and one actual test subject viewing cards with lines of varying length?
Solomon Asch conducted this classic experiment.
What year did Rutherford do his experiment?
The Geiger-Marsden experiment, which is also called the gold foil experiment or the Rutherford experiment, was conducted by Hans Geiger and Ernest Marsden in 1909, under Earnest Rutherford's direction. You need a link to the Wikipedia post on this ground-breaking experiment, and we've got one for you.
What is an experiment in which one variable is tested at a time?

What is an experiment in which only one variable is manipulated at a time?

What is an experiment in which only one manipulated at a time is called?
Controlled Experiment :Pcontrolled experiment.
What are the factors that can change in an experiment called?
Environmental factors if you cannot control them.Variable factors if you can control them.See link below for easy explanation:In an experiment the scientist is able to change the independent variable. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens. - See more at: http://www.chacha.com/question/what-part-of-an-experiment-is-the-factor-that-you-change#sthash.iyH25Jac.dpufIn an experiment the scientist is able to change the independent variable.
