# How do you know which variable is independent? ### How do you know which variable is independent?

The independent variable always goes on the x-axis, or the horizontal axis. The dependent variable goes on the y-axis, or vertical axis. As you can see, this is a graph showing how the number of hours a student studies affects the score she got on an exam.

### What is a independent variable example?

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.

### What type of variable is age?

Continuous variable There are 2 types of numerical variables: ● Continuous variable: A numerical variable that can take values on a continuous scale (e.g. age, weight).

### What is an example of an independent variable in an experiment?

The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.

### How is an independent variable different from a dependent variable?

A dependent variable is an outcome that depends on other factors, like the effects of a medicine depend on the dose. On the other hand, an independent variable is the cause of an outcome, and it isn’t affected by any other factors. Think of an independent variable as a cause that produces an effect.

### When do you have independent and dependent data?

But the data are independent if the weight and other variables for one person aren’t related to those for another. Sometimes, though, the data are dependent .

### Which is the independent variable in the graph?

X is the axis on which the independent or manipulated variable is graphed (the horizontal axis) Independent vs Dependent Variable Key Takeaways The independent and dependent variables are the two key variables in a science experiment.

### Why are constant variables important to the study of dependent variables?

Constant variables are important because they ensure that the dependent variable is changing because, and only because, of the independent variable so you can accurately measure the relationship between the dependent and independent variables.
