What does the science Dependent variable mean?
The dependent variable in a scientific experiment refers to the variable that is being measured or observed to determine the effect or relationship with the independent variable. It is called "dependent" because its value is believed to depend on the changes made to the independent variable.
What is the difference between indepedent and dependent variables?
In a science experiment, the independent variable is the one you change. For example: if you are doing an experiment on the impact of different types of soil on plant growth, the different types of soil would be your independent variable. The dependent variable is the outcome, or whatever the independent variable directly impacts. In this case, the dependent variable is the height of each plant.
What is a controlled expirement?
an experiment that can be controlled i did not know this That is not a good answer! A controlled experiment is: If you set up an experiment: Example: You have two plants. You want to know if fertilizing every day causes it to grow more. In your experiment everything has to be the same! Except one thing. You have to have the same type of dirt and pot and flower/vegetable. You have to water each of them every day. But, you fertilize ONE of them once a day until your results are clear to you, or when you want to stop testing. This way, you can see how the fertilizer effects the plant growth compared to just water every day. If you change more than one thing, like how much you water the plant, it is not a controlled experiment anymore. because then you won't know which variable (thing that you have changed) is taking effect. You wouldn't know if it was more water or the fertilizer, or both that is making the plant grow faster!

What are the variables in a scientific experiment?
There are 3 different variable. The independent variable is what you will be changing in the experiment and there should only be one. The dependent variable is what you will be measuring or observing. The controlled variable is what you will be keeping the same and there can be more than one. There is no limit on how many controlled variables you can have.
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 the difference between a factor and variable?
A factor of an experiment is a controlled independent variable; a variable whose the differences between means for different levels of one factor.
What are Variables in an experament?
A variable of an experiment is anything that is changed either deliberately, or as a result of changing something else. An independent variable is one that is changed to obtain a different result. A dependent variable is the thing that changes as a result of changing the independent variable. There is also the controlled variable, or just control, which does not change throughout the experiment. A test or a trial
What are the different variables during an experiment?
categorical variablesquantitative variablesordinal variablesthere are more common ones like...Controlled/constant variable-Variables that do not change at all!Manipulated/independent variable-Variables that change (intentionally) in order to see their effect on another variable.Responding/depending variable-Is measured quantitatively or qualitatively and is affected by the independent variables.Hope this helps.
What is an independent experiment?
In general, it is an experiment that is run by different experimenters, using different-but-similar equipment, in a different locale, and perhaps a different-but-similar testing protocol.
What is the difference between a controlled experiment and observation?
all it is is the uncontrolled experiment is a little bit different
What is the scientific definition for independent variable?
The independent variable in any item that is changed during a scientific experiment. The dependent variable is the object being tested. In an experiment testing the buoyancy of wood in different solutions, the different solutions would be the independent variable.
In a controlled experiment what term is used to describe the many factors that might be different between the experiment and control groups?
Variables
How do you identify a variable in an experiment?
In an experiment, usually one item will cause something else to vary in an observable manner and sometimes predictable way.A variable will be recognized as any factor, trait, or condition of the experiment that exists in varying amounts or types. There are independent variables, dependent variables, and controlled variables.An independent variable is one that is changed in an experiment. In order to perform a fair and subjective test one should consider only one independent variable during their experiment. As changes are made in the quantities of our independent variable, changes should be apparent that make observations different from other quantities of the independent variable.The focus of these observations is on the depenedent variable to see how it responds to the change made to the independent variable quantities. The new value of the dependent variable is caused by and depends on the value of the independent variable and is what we know as cause and effect.Not to be forgotten, we have the controlled variable which is a quantity that is maintained at a constant in the experiment so as to eliminate any confusion with cause and effect observations.
