Readers ask: Independent Variable Definition Science?

What is an independent variable science?

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.

What is an example of an independent variable in science?

Time as an Example of an Independent Variable

Question Independent Variable (What I change) Controlled Variables (What I keep the same)
How fast does a candle burn? Time measured, in minutes Use same type of candle for every test Wind—make sure there is none

What is the definition of a dependent variable?

The dependent variable is the variable being tested and measured in an experiment, and is ‘ dependent ‘ on the independent variable. An example of a dependent variable is depression symptoms, which depends on the independent variable (type of therapy).

What does independent and dependent variable mean in science?

The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.

What are the 3 types of variables?

There are three main variables: independent variable, dependent variable and controlled variables.

How do you know if two variables are independent?

You can tell if two random variables are independent by looking at their individual probabilities. If those probabilities don’t change when the events meet, then those variables are independent. Another way of saying this is that if the two variables are correlated, then they are not independent.

What are examples of independent?

The definition of independent is someone or something that is free from the influence or control of another. An example of independent is someone who lives on their own and supports themself. Free from the influence, guidance, or control of another or others; self-reliant.

What is variable and its types?

Variables represents the measurable traits that can change over the course of a scientific experiment. In all there are six basic variable types: dependent, independent, intervening, moderator, controlled and extraneous variables.

Is gender an independent variable?

An independent variable is used in statistics to predict or explain a dependent variable. For example, Age and Gender might be used as independent variables to predict the age of death or life expectancy (dependent variables ).

What is the best definition of dependent variable?

A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it “depends” on the independent variable.

What is dependent and independent variable in Research example?

An example of a dependent variable is how tall you are at different ages. 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.

Is gravity a dependent variable?

An independent variable is one that you would like to change, and the dependent variable is the response to the change of the independent variable. Water and light are considered independent because they can be changed, while gravity cannot be changed and is therefore not an independent variable.

Where do you plot the independent variable?

The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).

Is temperature an independent variable?

An independent variable is one that is unaffected by changes in the dependent variable. For example when examining the influence of temperature on photosynthesis, temperature is the independent variable because it does not dependent upon photosynthetic rate.
