What is the definition of idependent variable?
An independent variable is a part of an experiment that might change due to the outcome not being a desired result. The person conducting an experiment about how a medicine might affect a person, might change the number of people tested to gain more insight into the results. The independent variable in that situation would be the number of test subjects.
Which axis holds the independent variable?
An independant variable should always be on the x-axis of a graph and the dependant variable on the y-axis.
What should have only one independent variable?
i dont know i need help
In an experiment dealing with distance versus velocity which is the independent variable?
It will depend on the experiment. The answer is unclear because the question was not specific enough. There are experiments where either can be the independent variable. Your question is a bit vague, but there might be a solution. The best solution would be if you had your raw data, or remembered the structure of the experiment. Were you measuring velocity at specific distances, or were you measuring distances from set velocities? The set/specific values are your independent variables, and therefore the other quantity depends upon what you measured at those set intervals. The other possibility is in the wording of the question. If it is from your teacher, it is likely that the distance is the independent variable, as older terminology for graphing that uses versus, implies (not a guarantee, see below) that the independent variable is first (versus) the dependent, or x vs. y. Since the question states distance vs. velocity it can be assumed (again, not a guarantee) that distance is the independent and velocity is the dependent. You should ask for clarification of the whole versus phrasing, as some people don't know the order, and it is confusing. For example I had a high school teacher (and many other teachers) who stressed independent vs. dependent when graphing, because x comes before y. I had a college professor who stressed dependent vs. independent as the wording, because slope is y over x. So which is it, is the question; therefore it really is a poor way of describing the graph of the data. Regardless of which word goes before the versus, the independent is graphed on the x-axis, and the dependent is graphed on the y-axis. Next time ask for clarification phrased as _________ as a function of ___________. The first blank is of course the dependent variable, and the last blank is the independent variable.
What is a constant in a experiment?
Constants are the things that are kept the same each time one of the trials in the experiment is repeated. For example, constants could include the amount of water used, the brand of effervescent tablet used, the type of water used, and the fact that the water was not stirred. As many outside factors as possible should be kept constant in an experiment so that the researcher can be sure that any changes that occur do so because of the independent variable.
When the chemist designs his experiment what should be the only independent variable?
temperature
What should be the only independent variable?
In most real life cases, limiting an experiment to only one independent variable makes the whole experiment a waste of time. More often than not there are several independent variables.
What is The thing you change in an experiment?
The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
What does independent variable and dependent variable mean?
The independent variable is the variable that the scientist controls and can change in an experiment. There should be only one independent variable in an experiment; otherwise the cause-and-effect of the independent variable cannot be determined.The dependent variable is the variable that is affected by the independent variable.EXAMPLE:Students of the same age have been given different sleeping hours (the independent variable)The next day they are tested for their performance (the dependent variable).(Having students the same age is a third type of variable, called the constant variable or the control variable. It is deliberately kept the same to reduce any effects on the outcome.)
13 What is the relation between dependent and independent variables?
Independent variables are those that you change in an experiment. Dependent variables are the ones that you measure in an experiment. Dependent variables are influenced by the independent variables that you change, so they are dependent upon the independent variable. Generally, experiments should have only one independent variable.
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.
What does indepedent variable means in science?
The independent variable is the thing that changes with in the experiment to make it an experiment. For example, say I was doing an experiment on something such as "Which sponge brand can absorb the most water?" The independent variable would be the different sponge brands because it would be the thing that changes with in the experiment. Otherwise, if you didn't make an independent variable (the different sponge brands in this case) it wouldn't be an experiment because a sponge of the same brand should hold about the same amount of water as the others.
How many variables should you have when you start an experiment?
An experiment involves three types of variable.The independent variable is the one you are investigating. It is the one which you deliberately vary in the experiment. You should only have one independent variable.The dependent variable is the variable which you measure to get your results. Often there is only a single dependent variable but there can be more.All other variables must be controlled ie kept constant so they do not change the result. There are usually many control variables in an experiment.

What is a control variable in a science project?
It is the variables you will not change to keep the experiment a fair test, they should be kept constant to show how your independent variable affects your dependant variable.
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.
