What Is An Example Of A Continuous Variable?

Is salary a discrete or continuous variable?

Strictly speaking, it is a discrete variable, given that there is a basic unit of 1p below which measurements cannot be taken.

However, 1p is so small in relation to an annual salary (even the annual salary of a teacher) that in practice it is treated like a continuous variable..

What is the continuous variable?

Continuous variables can take on an unlimited number of values between the lowest and highest points of measurement. Continuous variables include such things as speed and distance. … Discrete data are associated with a limited number of possible values.

How do you know if a variable is continuous?

If you start counting now and never, ever, ever finish (i.e. the numbers go on and on until infinity), you have what’s called a continuous variable. If your variable is “Number of Planets around a star,” then you can count all of the numbers out (there can’t be an infinite number of planets).

What are two examples of continuous variables?

For example, when you measure height, weight, and temperature, you have continuous data. With continuous variables, you can calculate and assess the mean, median, standard deviation, or variance.

Is age continuous or discrete?

Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. For example, someone could be 22.32698457 years old or 22.32698459 years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.

What is the difference between a discrete and continuous variable?

“A discrete variable is one that can take on finitely many, or countably infinitely many values”, whereas a continuous random variable is one that is not discrete, i.e. “can take on uncountably infinitely many values”, such as a spectrum of real numbers.

How do you know if something is discrete or continuous?

Definition: A set of data is said to be continuous if the values belonging to the set can take on ANY value within a finite or infinite interval. Definition: A set of data is said to be discrete if the values belonging to the set are distinct and separate (unconnected values).

Which of the following are examples of continuous variables?

Examples of continuous variables are blood pressure, height, weight, income, and age.

What is an example of continuous?

The definition of continuous is going on without being interrupted. An example of continuous is a show that runs for 20 years. Uninterrupted in time, sequence, substance, or extent. … A continuous form fed into a printer.

Is gender a continuous variable?

Categorical variables contain a finite number of categories or distinct groups. Categorical data might not have a logical order. For example, categorical predictors include gender, material type, and payment method. … A continuous variable can be numeric or date/time.

Is heart rate a discrete or continuous variable?

Variables such as heart rate, platelet count and respiration rate are in fact discrete yet are considered continuous because of large number of possible values. Only those variables which can take a small number of values, say, less than 10, are generally considered discrete.

Which is not an example of continuous variable?

Height is not an example of a continuous variable.

Is intelligence a continuous variable?

Other examples of continuous variables include measurements of many physical traits, such as weight, length, speed, and temperature. Many psychological traits, such as intelligence, paranoia, extroversion, and creativity, are also continuous variables.
