What isdependent variable?
The dependent variable in an experiment is the thing that changes due to the experimentor changing the independent variable. Basically, its what you measure and record. For example: you create an experiment that observes the effects of the amount of sunlight on plants. You give one plant more sunlight than the other, leaving everything else exactly the same. That is your independent variable. Say you measure the height of each plant every week. Since the height is DEPENDENT on the amount of sunlight each plant got, the height is your dependent variable.
What is dependent variable mean?
It is what is being measured in the experiment. If you are doing an experiment to find out if "X" fertilizer works better than "Y" fertilizer, how would you find out? You would have to measure something. Probably the size of the plant over a period of weeks, taking weekly measurements so you could create a graph that shows progressive growth rate. Your dependent variable would be the size of the plants.
What is the independent variable of this question which color absorbs more heat black or red?
The independent variable is the variable that does not depend on other variables. In other words, the independent variable controls and varies the result of the experiment as the independent variable controls the dependent variable. For example, if you are experimenting on how long it takes water to boil, the independent variable would be time and the dependent variable would be temperature. Out of the two colours, black and red, black absorbs more heat than red. In fact, black is the colour that absorbs most heat out of all the colours. This is because if all of the seven colours from the light are absorbed, the combination becomes black. On the other hand, white reflects all seven colours from the light, so white is practically no colour at all.
What happens when more than one variable in an experiment is changed at a time?
Because you want to see how the experimental results change due to only that one variable change. If you used two variables, and the results varied, how would you know which variable contributed more to the change if at all? It can be done this way, but one variable at a time will allow you to make sense of your data much more efficiently.
A quanity that can have more than a single value is called?
Variable
What is scientific Dependent variable?
A dependent variable is a factor in an experiment that is influenced by another factor. An example might help to clarify. You are performing an experiment in which you are observing how sunlight affects plant height. Plant height is the dependent variable because it is dependent upon how much sunlight the plant receives. Sunlight is an example of an independent variable. It is not influenced by anything in this experiment, but may be changed to observe its effect on the dependent variable. It is possible to have more than one dependent variable in an experiment, but only one independent variable.
What variable is the part of the experiment that is affected by the independent variable that is being tested or the part that is changed by the person doing the experiment?
The variable of the experiment that is being tested or the part that is changed by the person doing the experiment is called the independent variable... Thank you for letting me answer goodbye... ;)
Why can you have only one variable in a experiment?
Actually, you have two - dependent and independent. But, you only have one variable because otherwise the answer wouldn't be accurate if you had more than one variable.
What variable is the part of an experiment that is being tested or the part that is changed by the person doing the experiment?
There are three kinds of variables in an experiment. The independent variable is what you change in the experiment. It is important that you have only one independent variable in your experiment. You would not be able to draw reliable conclusions from the experiment if you altered more than one experimental condition. The dependent variable is what you measure in the experiment. Unlike the independent variable, an experiment can have more than one dependent variable because variations in the independent variable can have many different effects. For example, you might measure length of leaves and weight of roots to assess the growth of radish plants. Dependent variables can include amounts as well as amount data. Such data cannot be measured but is still useful when you describe and compare it.
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 temperature a dependent variable?
yes. the independent variable is what you're testing. it can be a dependent variable depending on the experiment, however it could just as easily be the control if you keep it the same, or the independent if it is the variable you are manipulating rather than measuring. again it all depends on the experiment
In a experiment what is the independent variable?
The independent variable is the item that varies through out the experiment. The dependent variable is what changes due, and that is what we get our information from. For example: Patrick had a science experiment. He had 2 cups filled with dirt. Cup A had more water than Cup B. Each cup held the same type of seed and were both put in equal sunlight at equal amounts of times. What is the independent variable in this experiment? Answer: The water. The dependent variable would be the plant growth. *An easy tip to remember this is using the scientific title. "The effect of _______ on _______" The first blank is always the INDEPENDENT Variable, thus making the second blank a DEPENDENT. So in this experiment it would be "The effect of AMOUNTS OF WATER on PLANT GROWTH." This shows that the Independent Variable = Water Dependent = Plant Growth
Which variable is independent and which variable is dependent?
and independent variable is bigger than a dependent variable

Why does having more than one variable complicates the results of an experiment?
Because you can't be sure what about the variable is changing or how it changes. The different factors of the variable can also change the experiment in different ways, therefore making the experiment more complicated.
Can you have more than one responding variable?
It really depends on what the experiment is.
To be valid an experiment must not include?
more than one variable
