The relationship is a matter of cause and effect. An independent variable is given as one upon which another variable depends. So, for example, if you heat a metal pipe, the pipe expands. The amount of expansion is dependent upon the amount of heating that occurs, so expansion is the dependent variable, and the heating, which you may or may not control, is the independent variable. All it means is that if the independent variable ungoes a change, there is an associated and predictable change in the dependent variable. The two are linked inextricably, but one is cause, the other is effect, or to put it another way, you control the change in the dependent variable with input into the independent variable, but it doesn't normally work the other way around.

How do you separate dependent and independent variables?
I do it by using an "if/then" statement. The variable behind the "if" statement is the independent variable. The variable behind the "then" statement is the dependent variable. Example: y = 3x3 + 4x2 - 6x +1 So if you tried "if y = 2", you're still stuck on your "then" statement. You don't really know what x is, do you? But if you try "if x = 1", then you can determine right away that y = 2. So x is your independent variable and y is your dependent variable.
Is the random variable x equals 1 be stated that the random variable is discrete?
If x = 1 then X is not really a random variable but a constant.
How does the independent variable effect the dependent variable?
Haha are you cheating on your biology homework? Or is it HSPA? Al/geo perhaps? Well I'll help you anyway. It's simple really. The dependent variable 'depends' on the value the independent variable takes for its value.Say you have: y = 3x - 2This is the equation for a straight line right? Well, 'y' is the dep. variable, and 'x' is the indep. variable. So 'x' takes on any value you wish to give it. So if I assign a value of one (1) to x then y HAS to be 3*1 - 2 = 1.So y = 1 ONLY when x has been given its value.Understand?Think of it like this:When you go to a restaurant, you can ONLY get what the restaurant offers on its menu. You can't go to a hot dog joint and say "Hey....gimme a fillet mignon!".......right? Your meal DEPENDS on the menu.....your meal is 'dependent' upon the offerings of that restaurant...and the offerings of the restaurant are like the independent variable.Does that help????
What is 5x plus 16?
Can't really say. X is a variable and untill you define that variable, it can't be answered.
What is a number that is multiplied by the variable in an algerbraic expreesion?
Well, it really depends on the problem. A variable can be multiplied by just about any number.
Which of these is the independent (manipulated) variable for an experiment testing this hypothesis?
i really don't knkow
What is the independent variable for can a potato be used to generate electricity?
Well I really don't know.
The velocity of sound in air is independent of change in what variable?
The velocity of sound in air is independent of changes in frequency. Sound waves travel at a constant speed determined by the properties of the medium they are traveling through, such as air temperature and pressure.
Can you explain independent variable?
In a scientific experiment there are different variables. Variables being the factors that you can alter to obtain your results. The independent variable is the factor that you directly alter and the dependent variable is the one that is affected by this. E.g. You pull a cart over 1m and measure the time taken. The force you exert is the independent variable as you are controlling it and time is the dependent variable because it is the variable that is affected by the force you exert. Like if you pulled it really hard the time taken would be really short, and if you pulled it gently the time taken would be really long, etc.
Is a world globe an example of a variable?
A variable is something that can change in a experiment. A globe can't really change, so no. -yoda
What is the dependent and independent variable between time and temperature?
it depends really especially on the experiment you are doing.

When mixing corn starch and water in a science experiment which one is the independent variable?
Neither. You aren't really doing an experiment.
Why is an idependent variable needed?
An independent variable is a variable that you can control, you can choose and manipulate this variable. An example is an experiment looking at the growth of trees in the Dark, in a dimly lit room and in the direct sun. So you are going to put one plant in the sun, one in the dark and another in a dimly lit room. The independent variable is the location of the experiment, because this is what is being changed. The dependent variable may be the type of the plants and the height of the plants to begin with, The results on which is determined by the independent variable (ie amount of sunlight on the plants) So basically, without the independent variable you cannot really measure the full extent of the results. Uhm, I hope that makes sense, haha.
What is the purpose of the control group?
The purpose of a control group is to show what would happen under normal conditions. It serves as a comparison to the results you receive from the manipulation of the independent variable on the dependent variable. If a control group is present in an experiment, one can be more certain that the independent variable is really responsible for the observations.
Iām doing this project for science and I need to identify the variables but Iām really struggling I need to know the dependent independent and controlled variable my project is how does different amounts of salt affect a salt water circuit?
So if you're adding or taking away more salt to see the effect then the salt is your independent variable. If you're seeing how it effects your salt circuit then you need to find a way to measure those effects, whatever that it is your dependant variable. Your controlled variable is what you're keeping the same every time you add or take away more salt. Just remember: IV is what you change DV is what you record CV is what you keep the same Good luck!!
How do you draw a picture of a variable?
There are an infinite number of ways to draw a picture of a variable. This really depends on what the variable is and your perception of what it does.
