The outcome of the experiment may not be linked to any one specific variable.

Why is it important to have a control in a science experiment?

In order to be certain that the changing of the independent variable directly affects the dependent variable, a control must be taken where the independent variable is not changed-this ensures that whatever happens to the dependent variable happens because of the independent variable, and is not something that would happen anyway.


What happens if the experiment dose not confirm hypothesis?

This indicates that the hypothesis is probably incorrect and a new hypothesis needs to be developed. A negative result for a scientific experiment is just as important as a positive result and means that the experiment was a success.


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.


What usually happens if a scientific experiment generates new knowledge that doesn't agree with an existing theory?

The new knowledge is used to reevaluate the theory


What part of an experiment is a variable?

It's something that you measure (called the dependent variable) or something that you change to see what happens (the independent variable). for example, if you were conducting an experiment to see how many monkeys you saw when you left bananas where you could see them, the independent variable might be the number of bananas you put out, and the dependent variable might be the number of moneys you see in a given amount of time. The variables are named that way because (assuming that the number of bananas and the number of monkeys is in fact related) the number of monkeys DEPENDS on the nmber of bananas, whereas you just decide how many bananas to use on a particular run of the experiment.

What is the difference of independent variable and a dependent variable?

An independent variable is when you do not control what happens In an experiment,however; a dependent variable is when you actually control the experiment,

dependent variable


What is an idea about what happens to one variable when a second variable changes?

An idea about what happens to one variable when a second variable changes is called correlation. Correlation measures the strength and direction of the relationship between two variables. It can help us understand how changes in one variable may be associated with changes in another variable.


What is the dependent veritable dependent on?

A dependent variable is one that changes based on changes of the independent variable. Or we can say it depends on whatever happens to the independent variable.


Can someone explain dependent variable independent variable and controlled experiment in Kindergarten terms?

controlled experiment is a serious study of what happens everything is set up "right".independent variable is what starts a change.dependent variable is what changed after something started it.kindergartners have no sense of time, so don't bother explaining time derivatives to them..------Independant variable means what changes. Dependant variable means measurement. Controlled variable means what stays the same. (science)


Why is a control group important to have in a experiment?

A control group is the standard of comparison between what happens with the experimental variable and without the experimental variable.


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.

An experiment setup in which the independent variable is not present is called the?

When conducting experiments in science, it is important to have a baseline for knowing what happens if an independent variable is not present. In science, this is called the control experiment.


What happens in an controlled experiment?

In a controlled experiment, researchers manipulate one variable (independent variable) while keeping all other variables constant to observe the effect on another variable (dependent variable). This allows researchers to establish a cause-and-effect relationship between the variables being studied. Control groups are used to provide a baseline for comparison to ensure that any changes are a result of the independent variable being tested.


What is the dependent variable in a temperature experiment?

The Temperature is the Independent Variable (50 degrees, 100 Degrees etc.) Whatever happens as a result of the temperature change is the dependent variable.
