Why is it important to limit the variables in an experiment?
To understand this you need to remember that the independent variable is a condition that you can change, and the dependent variable is the outcome that you see. If you have two independent variables, and you change both during an experiment, how are you going to tell which one caused the change to the outcome? So, you only change one independent variable at a time.
Why is it so important to control variables in an experiment?
You need to control variables in an experiment so as to make sure that only the variable you are testing and changing is the one affecting the results of your experiment. For example, in an experiment to find the effect of light intensity on the rate of photosynthesis of plant, you'll change light by putting a plant in sun and another in dark but you must not change carbon dioxide level for both plants so by that you have controlled other variables in the experiment(variables which must be the same always in the experiment).
How many variables do you need in a science experiment?
Ideally, an experiment should test only one variable (the independent variable) at a time. If you have two or more variables changing at the same time you have no way of knowing which variable is causing your results.
Is the independent variable the thing you change?
Yes The independent variable is also known as the manipulated variable. In an experiment where you need to test different objects, the independent variable would be the different objects.
What is a controlled varable?
Controlled (or control) variables are things that are kept the same during an experiment. There are usually many- for example, when testing how light intensity affects photosynthesis, the controlled variable would be the type of plant used, or the color of the light.
Why is it importaint to controle variables in an experiment?
You need to control the variables because if you have two or more variables in an experiment you will never know which variable caused a change or not caused a change.
What is control variable?
what is an controlled variable. we need to know it for our science proformance asscement!!! From a friend in need!
When do you declare a variable method and a class final?
When There is No Need to Change the Values of the Variables In Entire lifetime of That variables then we must use that Variable as Final Variable.
Why would a scientists need to identify and control variables in an experiment?
A scientist would need to identify variables so you could know what to change and what to keep the same. A scientist would need to control variables so you can try to see exactly which factors are affecting the dependent variable (the thing you're measuring). Hope this helped! Because I have the exact same question on my homework!
What is constant variables?
Variables are items, which change their values during the execution of a program. Constants do not change the value during the execution of a program.

What are the independent dependent and control variables?
The independent variable is the thing you are changing/varying. The dependent variable is the thing you are measuring. This variable should be affected by the independent variable. Control variables are anything that must be kept constant. If there are any other factors which affect the dependent variable, then these need to be controlled so that they do not have any significant effect (basically ensuring that you are actually measuring the effects of the independent variable).
Are all scientific experiments controlled?
hi my name is Chasity im a freashmen in high school. this is the answer: Control means a factor which remains the same and doesn't change while variable is the other thing which can vary according to situation. hope that helped.
Why do you need to keep variables the same?
In programming, variables change all the time. In scientific testing you control variables to determine what other changes occur.
