Discrete variables are countable in a finite amount of time. For example, you can count the change in your pocket . You can count the money in your bank account. You could also count the amount of money in everyone’s bank accounts.
What is the example of discrete?
Discrete data is information that we collect that can be counted and that only has a certain number of values. Examples of discrete data include the number of people in a class, test questions answered correctly, and home runs hit.
Which of the following are examples of discrete random variables?
If a random variable can take only a finite number of distinct values, then it must be discrete. Examples of discrete random variables include the number of children in a family , the Friday night attendance at a cinema, the number of patients in a doctor’s surgery, the number of defective light bulbs in a box of ten.
What are 5 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 kind of variable is a discrete variable?
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 discrete series example?
Discrete series means where frequencies of a variable are given but the variable is without class intervals . Here the mean can be found by Three Methods. ... Here each frequency is multiplied by the variable, taking the total and dividing total by total number of frequencies, we get X.
What is discrete data with examples?
Discrete data is information that can only take certain values . These values don’t have to be whole numbers (a child might have a shoe size of 3.5 or a company may make a profit of £3456.25 for example) but they are fixed values – a child cannot have a shoe size of 3.72!
Is time a discrete variable?
Discrete time views values of variables as occurring at distinct, separate “points in time”, or equivalently as being unchanged throughout each non-zero region of time (“time period”)—that is, time is viewed as a discrete variable.
Is height a discrete variable?
A variable such as a person’s height can take on any value . ... Variables that can take on any value and therefore are not discrete are called continuous. Statistics computed from discrete variables have many more possible values than the discrete variables themselves.
What is an example of discrete quantitative variable?
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 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 are examples of discrete and continuous variables?
| Discrete Variable Continuous Variable | Examples: Number of planets around the Sun Number of students in a class Examples: Number of stars in the space Height or weight of the students in a particular class |
|---|
Is money discrete or continuous?
A continuous distribution should have an infinite number of values between $0.00 and $0.01. Money does not have this property – there is always an indivisible unit of smallest currency. And as such, money is a discrete quantity .
What are two examples of continuous variables?
You often measure a continuous variable on a scale. 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 gender a discrete or continuous variable?
| 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 are examples of quantitative variables?
- High school Grade Point Average (e.g. 4.0, 3.2, 2.1).
- Number of pets owned (e.g. 1, 2, 4).
- Bank account balance (e.g. $100, $987, $-42.
- Number of stars in a galaxy (e.g. 100, 2301, 1 trillion) .
- Average number of lottery tickets sold (e.g. 25, 2,789, 2 million).
