# Why do you called independent variable independent variable?

because it is independent

### What is the variable that is changed on purpose in a scientific experiment called?

The variable that the experimenter deliberately changes is called the independent variable. The thing you are observing as a result of the different 'values' or 'conditions' of the independent variable is called the dependent variable. If the experiment is well controlled, then you can have some confidence that changes in the dependent variable have come about directly as a result of your changes to the independent variable.

### What are dependent and independent variables and how are they usually related to each other in a problem or situation?

a DEPENDENT variable is one of the two variables in a relationship.its value depends on the other variable witch is called the independent variable. the INDEPENDENT variable is one of the two variables in a relationship . its value determines the value of the other variable called the independent variable.

### What are independent and dependent variables?

The independent variable is also called an experimental variable. It is the variable being manipulated in the experiment in order to show the effect on the dependent variable. The dependent variable is also called the response variable. It is the variable being observed in the experiment. A change in the independent variable is what causes the change (if any) in the dependent variable, which is the purpose of the experiment.

### What is the difference between a dependant and independent variable in an experiment?

The independent variable is what you did differently in the experiment compared to the controlled experiment; it's also called manipulated variable. The dependent variable is what changed in the experiment as a result of the independent variable; it's also called the responding variable x hope this helps :)

### What is the difference between dependent and independent variables?

The independent variable is the variable being manipulated in the experiment in order to show the effect on the dependent variable. It is also called the experimental variable. The dependent variable is the variable being observed in the experiment. Changes in the dependent variable as a result of changes in the independent variable are observed, which is the purpose of the experiment. Dependent variable is also called the response variable.

### What does dependent and independent mean in math terms?

A dependent variable is one in whose experimental or analytical value is determined by the value of the independent variable. An independent variable is not determined by any other variable, but rather is an input value. For example in the equation y = 3x y is dependent and determined by the value of the independent variable x

### 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…
