Controlled variable = One that you are able to keep constant throughout your experiment that would otherwise effect your results.
Uncontrolled = A variable that could effect your results but you have little to no ability to control it.
Independant variable = The variable that you will be changing or allowing to change in order to get your results
Dependant variable = The variable that you are actually recording. The whole point of your experiment.
For example if I was measuring how many rabbits there were on three differant fields. The different fields would be the independant variables and the number of rabbits would be my dependant variable.What is the difference between controlled variables, independdent and dependent variables?
In an experiment, the experimenter wants to test ONE thing; this is the independent variable. The response, which depends on changing the independent variable, is the dependent variable. A controlled variable is anything else which may change during an experiment, but the experimenter wants to remain constant.
For example, consider an experiment to determine the effect of a new fertilizer on making a plant grow taller. The INDEPENDENT VARIABLE is the presence of the fertilizer; that is the variable controlled by the experimenter. The DEPENDENT VARIABLE is the height of the plants with or without the fertilizer, because it dependsd on the independent variable. The CONTROLLED VARIABLES would be the amount of sunlight on the plants, the amount of water, the type of soil, etc.,What is the difference between controlled variables, independdent and dependent variables?
The Independent part is what you, the experimenter, changes or enacts in order to do your experiment. The dependent variable is what changes when the independent variable changes

Why do need to control some variables?
Because that's what variables do... vary, according to manipulation.
What is the manipulated, responding, and the controlled variables in this question?
Here's the question: If I don't make any changes to the chicken embryo, then the chicken embryo will fully develop with health problems.What is the manipulated, responding, and the controlled variables in this question?

What is are the dependant variables & independant variables, and controlled variables in thi science experimen?
im investigating and observing whether different colours are equally visible in the dark.
im using coloured paper and the dial on my light switch to adjust the brightness %26amp; dimness. umm im also using people in my family to determine what they see for the results
thanks. :)What is are the dependant variables %26amp; independant variables, and controlled variables in thi science experimen?
The independent is the lights vs. dark because your controlling that to see its effect on the dependent variable, which in your case is the visibility of the colors in light vs. dark.gas mask

I forgot what the control, independant and dependent variables are!!!?
Can someone give me a definition of each and explain their purpose? I don't remember what each of them mean! Thanks.I forgot what the control, independant and dependent variables are!!!?
The control is the baseline for your experiment.
Independent variables are those whose values are controlled or selected by the experimenter.
Dependent variables are those that change based on the independent variables.I forgot what the control, independant and dependent variables are!!!?
- control variable are the things that you keep the same in order to make it a fair test
- independant variable is the thing that you change in your experiment so the thing you are investigating
- dependant is the thing you measure so the results which you record in your experiment
The dependent variable is the the event/item being measured to see if it is different when the independent variable is changed.
One way I remember the difference is that the outcome (dependent variable) DEPENDS on the INput (independent variable).
A control variable is a factor that is held constant so that it won't affect the impact that the independent variable makes.
Here is an example of a simple experiment. Let's say we want to test if a basketball bounces higher than a tennis ball when it is dropped.
The independent variable is the type of ball.
The dependent variable is the height of the bounce.
We might test this by dropping balls off of a balcony onto the driveway. To check to see if a basketball bounces higher than a tennis ball, we need to control for certain variables.
We will want to control for the height from which they are dropped. (if one ball falls 10 feet and another 11, how do your really know it is the ball type that made the difference in the bounce?
We also want to control the surface that the balls land on. (eg Make sure both land on concrete as opposed to one landing on dirt or black top or wood.) You also may want to control for things like temperature and weather (would wind or rain affect a bounce?).
The easiest way to control for all of these factors would be to drop both balls at the same time from the same balcony, side by side.
To repeat, the ball type is the input and factor that is purposely varied. The height of the bounce is the dependent variable. It may be affected by the type of ball.
Height, speed, surface, weather, etc are control variables.
The control is the baseline for your experiment.

I was assigned to think of a experiment that has a control, independent and dependent variables!!?
2. A social psychologist thinks that people are more likely to conform to a large crowd than to a single person. To test this hypothesis, the social psychologist had either one person or five persons stand on a busy walking path on campus and look up. The psychologist stood nearby and counted the number of people passing by who also looked up.
Independent variable: Size of group (5 people or 1 person)
Dependent variable: Conformity (measured by number of people looking up)
Experimental group: People passing 5 person group
Control group: People passing single person. (This group gets “less” of the independent variable)
Independent variable: Size of group (5 people or 1 person)
Dependent variable: Conformity (measured by number of people looking up)
Experimental group: People passing 5 person group
Control group: People passing single person. (This group gets “less” of the independent variable)
Control variables?
I'm not sure what they are, can someone please give me a few examples of what they could be?
thanksControl variables?
