## Is X or Y the controlled variable?

independent variable

If you are talking about determining ordered pairs to be graphed, the variable that is under your control is the x variable. It is called the independent variable. The variable that results from the independent variable is the y variable.

### How do you tell if it’s an independent or dependent variable?

An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.

#### Is X always the independent variable?

The independent variable is always displayed on the x-axis of a graph, while the dependent variable appears on the y-axis. Time is a common independent variable, as it will not be affeced by any dependent environemental inputs.

**What is Y variable?**

The Y variable represents the effect or outcome in a causeand-effect relationship, whereas X usually denotes the cause or independent variable. The Y variable is generally shown on the left-hand side of regression equations; therefore, it is sometimes referred to as a left-side variable.

**How do you find the dependent variable?**

The dependent variable is the one that depends on the value of some other number. If, say, y = x+3, then the value y can have depends on what the value of x is. Another way to put it is the dependent variable is the output value and the independent variable is the input value.

## Why is y the dependent variable?

In mathematical terms, we call a variable independent if its value can be set arbitrarily to get a result. This is known as the input of a function. Mentor: That’s right, y is the dependent variable because we do not set a value of y directly; instead, we set a value of x and use that to find the value of y.

### Which is the independent variable?

The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.

#### What axis does the dependent variable go on?

Choose your x and y carefully. Scientists like to say that the independent variable goes on the x-axis (the bottom, horizontal one) and the dependent variable goes on the y-axis (the left side, vertical one).

**How do you measure an independent variable?**

The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation and the independent variables are the inputs to that measurement. In a simple mathematical equation, for example: a = b/c the independent variables, b and c , determine the value of a .

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

In science and math, an independent variable is a variable or value that is changed, altered, or entered, while a dependent variable is a variable or value that is being observed. You may manipulate or control independent variable, but the dependent variable cannot be touched and can simply be examined.

## What is a true independent variable?

Key Takeaways: Independent Variable The independent variable is the factor that you purposely change or control in order to see what effect it has. The variable that responds to the change in the independent variable is called the dependent variable. It depends on the independent variable. The independent variable is graphed on the x-axis.
