What is a discrete variable in statistics?
A discrete variable is a variable whose value is obtained by counting. Examples: number of students present. number of red marbles in a jar. number of heads when flipping three coins.
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.
Can you give 5 examples of discrete random variables?
number of boreal owl eggs in a nest. number of times a college student changes major. shoe size. weight of a student.
What 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 is discrete example?
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 best example for discrete data?
Discrete vs continuous data
| Discrete data | Continuous data |
|---|---|
| Some common examples of discrete data are the number of students, the number of children, the shoe size, and so on | Some common examples of continuous data are height, weight, length, time, temperature, age, and so on |
Is eye color discrete or continuous?
Discrete data is organised in separate categories and is often presented in a bar chart. Examples of types of discrete data include: eye colour, hair colour, number of people in a shop, favourite chocolate bar. These values are distinct.
Is foot length discrete or continuous?

What are examples of discrete variables and continuous variables?
A discrete variable is always numeric. For example, the number of customer complaints or the number of flaws or defects. Continuous variable Continuous variables are numeric variables that have an infinite number of values between any two values. A continuous variable can be numeric or date/time.
What are some examples of discrete data?
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. Tables and graphs are two ways to show the discrete data that you collect.
What is the difference between discrete and continuous variables?
Key Differences Between Discrete and Continuous Variable. On the other hand, Continuous variables are the random variables that measure something. Discrete variable assumes independent values whereas continuous variable assumes any value in a given range or continuum. A discrete variable can be graphically represented by isolated points.
