## What is discrete variable in Research example?

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.

## What are 5 examples of discrete data?

Examples of discrete data:

• The number of students in a class.
• The number of workers in a company.
• The number of parts damaged during transportation.
• Shoe sizes.
• Number of languages an individual speaks.
• The number of home runs in a baseball game.
• The number of test questions you answered correctly.

What are 3 examples of discrete data?

Examples of discrete data include the number of people in a class, test questions answered correctly, and home runs hit. Tables, or information displayed in columns and rows, and graphs, or structured diagrams that display the relationship among variables using two axes, are two ways to display discrete data.

### What are examples of nominal variables?

Examples of nominal variables include: genotype, blood type, zip code, gender, race, eye color, political party.

### Which are discrete 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 random variable is a variable whose value is a numerical outcome of a random phenomenon. A discrete random variable X has a countable number of possible values.

What is best example for discrete data?

Shoe Size available in the market is an example of Discrete Data. Shoe Size available in the market is an example of Discrete Data. Discrete Variables can take values within a range. Discrete Variables can take values within a range.

#### Which is a discrete 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.

#### Is age discrete or continuous?

Technically speaking, age is a continuous variable because it can take on any value with any number of decimal places. What is this? If you know someone’s birth date, you can calculate their exact age including years, months, weeks, days, hours, seconds, etc. so it’s possible to say that someone is 6.225549 years old.

Is gender a nominal variable?

A good example of a nominal variable is sex (or gender). Information in a data set on sex is usually coded as 0 or 1, 1 indicating male and 0 indicating female (or the other way around–0 for male, 1 for female).

## Is gender a discrete variable?

What is the difference between discrete and continuous?

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 variable is a quantity whose value changes. A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring.

#### Which variable keeps track of the outcome of a random experiment?

If you want to quantify this data, you can assign 1 for heads and 0 for tails and compute the total score of a random coin tossing experiment. In this case, the variable that keeps track of the outcome is a discrete variable.
