What defines a discrete variable?
a variable that may assume only a countable, and usually finite, number of values.
What are examples of discrete and continuous variables?
Difference between Discrete and Continuous Variable
| 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 |
What is an example of a discrete variable in statistics?
Discrete Variables
A variable is said to be a discrete variable if it takes either finite or countably infinite values. For example the number appearing on uppermost face of die is a discrete variable because only finitely many values are possible (those values being 1,2,3,4,5 and 6).
Which of these is an example of a discrete variable?
The answer is the gender of each student in a psychology class is an example of a discrete variable.
What are 3 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.
Which of the following is an example of discrete data?
What is the difference between discrete and 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 |
What is the example of discrete?
What are 5 examples of discrete data?
What is difference between discrete and continuous variable?
Discrete and continuous variables are two types of quantitative variables: Discrete variables represent counts (e.g. the number of objects in a collection). Continuous variables represent measurable amounts (e.g. water volume or weight).
What is difference between discrete and continuous?
Discrete data is the type of data that has clear spaces between values. Continuous data is data that falls in a constant sequence. Discrete data is countable while continuous — measurable.
Which data is discrete?
Discrete data is a count that involves integers — only a limited number of values is possible. This type of data cannot be subdivided into different parts. Discrete data includes discrete variables that are finite, numeric, countable, and non-negative integers.
What are the 3 example of discrete random variable?
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.
Is age a discrete variable?
– Is age discrete or continuous? Age is a discrete variable when counted in years, for example when you ask someone about their age in a questionnaire. Age is a continuous variable when measured with high precision, for example when calculated from the exact date of birth.
Is age discrete or continuous?
continuous
– Is age discrete or continuous? Age is a discrete variable when counted in years, for example when you ask someone about their age in a questionnaire. Age is a continuous variable when measured with high precision, for example when calculated from the exact date of birth.
What are examples of continuous variables?
Continuous variables
A variable is said to be continuous if it can assume an infinite number of real values within a given interval. For instance, consider the height of a student. The height can’t take any values. It can’t be negative and it can’t be higher than three metres.
What is discrete example?
Some discrete data examples are: The number of customers who bought different items. The number of computers in each department. The number of items you buy at the grocery store each week.
What is continuous and discrete random variable?
A random variable is a variable whose value depends on all the possible outcomes of an experiment. A continuous random variable is defined over a range of values while a discrete random variable is defined at an exact value.
Is gender discrete or continuous?
Variable Reference Table : Few Examples
| Variable | Variable Type | Variable Scale |
|---|---|---|
| Length | Continuous | Ratio |
| Product ID in Numbers | Discrete | Nominal |
| Gender | Discrete | Categorical |
| Gender as Binary 1/0 Coding | Discrete | Categorical |
What are 3 examples of qualitative variables?
Qualitative Variable (Categorical Variable): Definition and Examples
- Eye colors (variables include: blue, green, brown, hazel).
- States (variables include: Florida, New Jersey, Washington).
- Dog breeds (variables include: Alaskan Malamute, German Shepherd, Siberian Husky, Shih tzu).
What is the meaning of discrete and continuous?
Discrete data is the type of data that has clear spaces between values. Continuous data is data that falls in a constant sequence. Discrete data is countable while continuous — measurable. To accurately represent discrete data, the bar graph is used.
What is an example of a discrete qualitative variable?
Here are some examples of discrete variables: Number of children per family. Number of students in a class. Number of citizens of a country.
