What are examples of independent and dependent variables?

The type of soda – diet or regular – is the independent variable. The level of blood sugar that you measure is the dependent variable – it changes depending on the type of soda.

What are independent variables in science?

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.

What is an dependent variable in science examples?

The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores since that is what is being measured.

How do you know when a variable is independent or dependent?

The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.

What are examples of independent and dependent variables? – Related Questions

How do you know if two variables are independent or dependent?

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.

Can you have 2 dependent variables?

Researchers in psychology often include multiple dependent variables in their studies. The primary reason is that this easily allows them to answer more research questions with minimal additional effort.

Is color a dependent variable?

It may be something that is already there and is fixed, something you would like to evaluate with respect to how it affects something else, the dependent variable like color, kind, time. A dependent variable is what you measure in the experiment and what is affected during the experiment.

How many dependent variables do you want in an experiment?

A well-designed experiment normally incorporate one or two independent variables, with every other possible factor eliminated, or controlled. There may be more than two dependent variables in any experiment.

What is another name for the independent variable?

Independent variables are also called “regressors,“ “controlled variable,” “manipulated variable,” “explanatory variable,” “exposure variable,” and/or “input variable.” Similarly, dependent variables are also called “response variable,” “regressand,” “measured variable,” “observed variable,” “responding variable,” “

Is time a dependent variable?

Time is a common independent variable, as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.

Is temperature a dependent variable?

Think of if you were looking at how temperature changed with the time of day. It’s hotter in the middle of the day than at either morning or night. So, the temperature depends on the time. So, the temperature is dependent, and the time is independent.

What is a dependent variable simple?

A dependent variable is a variable whose value depends upon independent variable s. The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation. The dependent variable is sometimes called “the outcome variable.” In a simple mathematical equation, for example: a = b/c.

Which one 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.

Is smoking a dependent or independent variable?

Smoking as an independent variable in a multiple regression analysis upon birth weight and gestation. Am J Public Health Nations Health. 1966 Apr;56(4):626-33. doi: 10.2105/ajph.

What is a dependent variable of cigarette smoking?

Independent Variable: __Amount of cigarette smoking__ Dependent Variable: __Risk of lung cancer___

What are control variables?

A control variable is anything that is held constant or limited in a research study. It’s a variable that is not of interest to the study’s aims but is controlled because it could influence the outcomes.

Can non smokers hold their breath longer than smokers?

Results – The mean breath holding time among smokers was 34.85 seconds, whereas the mean breath holding time was 46.61 seconds among non smokers.

How long should a healthy person be able to hold their breath?

In short, the average healthy person can hold their breath for 3-5 minutes. A person’s ability to hold their breath can be increased if the person exercises regularly, is a diver or professional athlete. Holding your breath can cause high blood pressure, brain damage, or even fainting.

Is it healthy to hold your breath?

For most people, it’s safe to hold your breath for a minute or two. Doing so for too much longer can decrease oxygen flow to the brain, causing fainting, seizures and brain damage. In the heart, a lack of oxygen can cause abnormalities of rhythm and affect the pumping action of the heart.
