that doesn't make sense
An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.
Independent variables answer the question "What do I change?"Dependent variables answer the question "What do I observe?"Controlled variables answer the question "What do I keep the same?"
It could be the experimenter, someone else (in a double blind experiment) or nobody.
When graphing in science, the independent variable is the variable graphed on the x-axis; the dependent variable is the variable graphed on the y-axis. To determine the name of the variable, one only needs to find the variable changed by the other variable and the variable remaining unaffected by the other variable. For example, someone wanted to find the the increased temperature of water over a stove during a period of time. Since increasing water temperature cannot affect time and increasing time can affect the water becomes the dependent variable and time becomes the independent variable.
The answer depends on whether or not you (or someone else) have any control over it. If someone has control then they can choose the values. If not, you get what the observations give you.
In math, The independent variable is the variable having something done to it.examples:a = 2bb2 + 4 = aa = 5 - bIn each of these, b is the independent variable and a is the dependent variable. You can make b be whatever you want it to be but a is dependent on what be is set to. In science, the independent variable is the one factor that you change in an experiment.In a scientific experiment, you change one thing (the independent variable) and measure any consequent change in another thing (called the dependent variable, because its value depends on the independent variable). All other variables must be held constant to avoid confusing the issue.In practice, the independent variable is either what you alter (such as the acidity, or the temperature) or it is time passing (for example, in an experiment in which you measure the changes in someone's blood sugar levels at various times after eating a meal)._______________________________________________________________________________________________________A factor or phenomenon that causes or influences another associated factor or phenomenon called a dependent variable. For example, income is an independent variable because it causes and influences another variableconsumption. In a mathematical equation or model, the independent variable is the variable whose value is given. In an experiment, it is the controlled condition(that is allowed to change in a systematic manner) whose effect on the behaviorof a dependent variable is studied. Also called controlled variable, explanatory variable, or predictor variable. Refer to Business dictionary for more information.
controlled experiment is a serious study of what happens everything is set up "right".independent variable is what starts a change.dependent variable is what changed after something started it.kindergartners have no sense of time, so don't bother explaining time derivatives to them..------Independant variable means what changes. Dependant variable means measurement. Controlled variable means what stays the same. (science)
Question: What's a variable?Answer: A variable is an object, event, idea, feeling, time period, or any other type of category you are trying to measure. There are two types of variables-independent and dependent.Question: What's an independent variable?Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age. In fact, when you are looking for some kind of relationship between variables you are trying to see if the independent variable causes some kind of change in the other variables, or dependent variables.Question: What's a dependent variable?Answer: Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.Many people have trouble remembering which is the independent variable and which is the dependent variable. An easy way to remember is to insert the names of the two variables you are using in this sentence in they way that makes the most sense. Then you can figure out which is the independent variable and which is the dependent variable:(Independent variable) causes a change in (Dependent Variable) and it isn't possible that (Dependent Variable) could cause a change in (Independent Variable).For example:(Time Spent Studying) causes a change in (Test Score) and it isn't possible that (Test Score) could cause a change in (Time Spent Studying).We see that "Time Spent Studying" must be the independent variable and "Test Score" must be the dependent variable because the sentence doesn't make sense the other way around.

Examples of independent variables include age, gender, temperature, amount of sunlight, type of treatment administered, and level of education. These variables are manipulated or selected by the researcher to observe their effect on the dependent variable in an experiment.
