How many minimum values of independent variable you should consider and why?

The absolute minimum number would be three values.
If you have two or one, there are an infinite number of lines (straight or curved) which could be drawn through them on a graph. You would have no way of knowing which line was correct.
If you have (at least) three values then you can see whether or not they form a straight line.
In practice, you should have at least 5 or 6 values for your independent variable to be reasonably sure of the correct shape of the graph.

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 is the meaning of dipendent variable?
I hope this helps you out a lot. If you are asking what a dependent variable is, here is your answer: A dependent variable is a variable which would be the output of the experiment. The value of the dependent variable depends on the value of the independent variable. If you are asking what a dependent variable does, here is your answer: A dependent variable shows you the output of the experiment. It shows you the independent variable's function. If you have learned that in Math, you should understand. Source(s): I'm a Science and Math whiz.
What is a controlled variable in a science fair 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.
What is the only variable that should be changed to test?
Independent variable
What is the independent variable when graphing the density of a solid?
Mass is the independent variable and should be plotted on the x-axis.
On which axis of a graph should the independent variable be graphed?
the independent variable goes on the x-axis the dependent goes on the y-axis
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.)

What are the independent dependent and control variables?
The independent variable is the thing you are changing/varying. The dependent variable is the thing you are measuring. This variable should be affected by the independent variable. Control variables are anything that must be kept constant. If there are any other factors which affect the dependent variable, then these need to be controlled so that they do not have any significant effect (basically ensuring that you are actually measuring the effects of the independent variable).
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.
