Question: What Kind Of Variable Is Smoking?

Is time an independent variable?

If time is one of your variables, it is the independent variable.

Time is always the independent variable.

The other variable is the dependent variable (in our example: time is the independent variable and distance is the dependent variable)..

What type of variable is a percentage?

Nominal variables are often summarized as proportions or percentages. For example, if you count the number of male and female A.

What kind of variable is gender?

A categorical variable (sometimes called a nominal variable) is one that has two or more categories, but there is no intrinsic ordering to the categories. For example, gender is a categorical variable having two categories (male and female) and there is no intrinsic ordering to the categories.

What is difference between dependent and independent variable?

The independent and dependent variables are the two key variables in a science experiment. The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect.

Is height an independent variable?

The assignment of dependent and independent variables depends on the specific purpose of the study. For example, height might be an independent variable in the context stated above but a dependent variable in a study on the effect of nutrition on growth rates.

Is smoking an independent variable?

For example, in the research on cigarette-smoking and lung cancer, cigarette-smoking, which has already been done by many subjects, is the independent variable.” (Kerlinger, 1986, p. … Smoking “depends” on lung cancer.

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 are the four types of variables?

You can see that one way to look at variables is to divide them into four different categories ( nominal, ordinal, interval and ratio). These refer to the levels of measure associated with the variables. In everyday usage the convention is to then use the level of measure to refer to the kind of variable.

What is an independent variable example?

Two examples of common independent variables are age and time. … They’re independent of everything else. The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It’s what changes as a result of the changes to the independent variable.

What type of variable is income?

Continuous Variables A continuous variable can take on any score or value within a measurement scale. In addition, the difference between each of the values has a real meaning. Familiar types of continuous variables are income, temperature, height, weight, and distance.

What is an independent variable in algebra?

A variable in an equation that may have its value freely chosen without considering values of any other variable. For equations such as y = 3x – 2, the independent variable is x. The variable y is not independent since it depends on the number chosen for x.

What type of variable is age?

Mondal[1] suggests that age can be viewed as a discrete variable because it is commonly expressed as an integer in units of years with no decimal to indicate days and presumably, hours, minutes, and seconds.

What is variable example?

A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item. Age, sex, business income and expenses, country of birth, capital expenditure, class grades, eye colour and vehicle type are examples of variables.

Is force a dependent variable?

The strength of a force is defined by the rate at which it can speed up one kilogram of mass. When two variables are related, one of the variable is free to roam so it is called the independent variable. The other variable depends on the first, so it gets the name dependent.

What kind of variable is height?

A variable that is “a number”. Age, height, score on an exam, response on a Likert scale on a survey are all continuous variable. It can be ordinal, interval or ratio types. Examples of continuous variables are blood pressure, height, weight, income, and age.

What is an independent variable easy definition?

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.

Is money an independent variable?

The independent variable is the number of boxes of cookies you buy. The dependent variable is the amount of money you spend on the cookies. The independent variable is the amount of money you spend on the cookies.
