# What is the difference between discrete and continuous variables?

## What is the difference between discrete and continuous variables?

A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring. A continuous random variable X takes all values in a given interval of numbers.

## What is the difference between quantitative discrete and continuous?

What is the difference between discrete and continuous data? Discrete data is a numerical type of data that includes whole, concrete numbers with specific and fixed data values determined by counting. Continuous data includes complex numbers and varying data values that are measured over a specific time interval.

What is continuous variable in quantitative research?

Continuous variables are variables that can take on any value within a range. Continuous variables are also considered metric or quantitative variables, where the variable can have an infinite number or value between two given points. Continuous variables are often measured in infinitely small units.

### What is an example of quantitative discrete data?

A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation. Examples of discrete quantitative variables are number of needle punctures, number of pregnancies and number of hospitalizations.

### Is gender a discrete or continuous variable?

Variable Reference Table : Few Examples

Variable Variable Type Variable Scale
Gender Discrete Categorical
Gender as Binary 1/0 Coding Discrete Categorical
True/False Discrete Categorical
Phone Number Discrete Nominal

What is the difference between discrete and continuous data?

The difference between discrete and continuous data can be drawn clearly on the following grounds: Discrete data is the type of data that has clear spaces between values. Continuous data is data that falls in a continuous sequence. Discrete data is countable while continuous data is measurable.

#### What is the difference between discrete and continuous distribution?

A probability distribution may be either discrete or continuous. A discrete distribution means that X can assume one of a countable (usually finite) number of values, while a continuous distribution means that X can assume one of an infinite (uncountable) number of different values.

#### What are some examples of continuous variables?

Continuous Variable. 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 example of a quantitative variable?

A quantitative variable can be measured and has a specific numeric value. Examples of quantitative variables include height, weight, age, salary, temperature, etc. Any variables that are not quantitative are qualitative, or a categorical variable.

In some contexts a variable can be discrete in some ranges of the number line and continuous in others. A continuous variable is a variable whose value is obtained by measuring, ie one which can take on an uncountable set of values.

## How is the value of a continuous variable obtained?

It is a variable whose value is obtained by counting. It is a variable whose value is obtained by measuring. Range of specified numbers is complete. Range of specified numbers is incomplete, i.e. infinite. It assumes a distinct or a separate value. It assumes any value between two values.

## What’s the difference between continuous and interval data?

Interval/ratio data are also called “quantitative” data. A further division of interval/ratio data is between discrete variables, whose values are necessarily whole numbers or other discrete values, such as population or counts of items. Continuous variables can take on any value within an interval, and so can be expressed as decimals.

Is the age of a person a continuous variable?

Age could also be considered a continuous variable, though we often treat it as a discrete variable, by rounding it to the most recent birthday. There is a technical difference between interval and ratio data. For interval data, the interval between measurements is the same, but ratio between measurements is not known.
