Question: What Is The Independent Variable In BMI?

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..

What is the 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.

What is the independent variable between height and weight?

The independent variable is average height. The dependent variable is weight. Think of it this way: does being taller cause a person to weigh more, or does being heavier cause a person to be taller? The assignment of dependent and independent variables depends on the specific purpose of the study.

Is age an independent variable?

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 is meant by dependent variable?

Dependent Variable The variable that depends on other factors that are measured. These variables are expected to change as a result of an experimental manipulation of the independent variable or variables.

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.

When can we consider if a variable is dependent and independent?

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.

What is the treatment that eliminates the independent variable?

Control Treatment22 Cards in this SetControlled VariablesVariables that are kept constant during the experiment (variables not being manipulated).Level of treatmentAppropriate values to use for the independent variable.ControlTreatment that eliminates the independent variable or sets it at a standard value.19 more rows

Is body weight an independent variable?

Calorie intake is your independent variable and weight is your dependent variable. You can choose the calories given to participants, and you see how that independent variable affects the weights. You may decide to include a control variable of age in your study to see if it affects the outcome.

What are the 3 types of variables?

A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.

What is variable in Research example?

Variable Definition in Research For example, an experimenter might compare the effectiveness of four types of fertilizers. In this case, the variable is the ‘type of fertilizers’. A social scientist may examine the possible effect of early marriage on divorce.

Is BMI independent or dependent?

For example, suppose we want to assess the association between total cholesterol (in milligrams per deciliter, mg/dL) and body mass index (BMI, measured as the ratio of weight in kilograms to height in meters2) where total cholesterol is the dependent variable, and BMI is the independent variable.

What does the independent variable measure?

Independent and Dependent Variables: An independent variable is the variable you have control over, what you can choose and manipulate. … 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.

How do you know what the dependent variable is?

One way to help identify the dependent variable is to remember that it depends on the independent variable. When researchers make changes to the independent variable, they then measure any resulting changes to the dependent variable.

What is the independent variable of your level of happiness?

Income was used as a factor (independent variable) to predict happiness which was the dependent variable. Both income and happiness were interval level data. The two variables were developed based a five-point Likert scale.
