What is an example discrete variable?
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. students’ grade level.
How do you know if a variable is discrete or continuous?
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 one example of a continuous variable?
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.
Which of the following is an example of a continuous variable?
Continuous variables are variables whose value between two values is infinite. They can be numerical, time or date. Some examples are temperature and length.
What are two examples of continuous variables?
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. For example, the length of a part or the date and time a payment is received.
Is age a discrete variable?
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.
Is gender discrete or continuous?
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 are discrete data?
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 Money discrete or continuous?
discrete variable
Because money comes, in clear steps of one cent, it’s a discrete variable, as well. In theory, the restaurant could make any amount of money. However, the revenue is still discrete.
Is gender a continuous variable?
Gender can be a continuous variable, not just a categorical one: Comment on Hyde, Bigler, Joel, Tate, and van Anders (2019)
Is height a discrete variable?
As a result, we can say, that height is a continuous variable. Because we cannot define a specific set of values, that incorporate every possible height of any human being.
Is hair color continuous or discrete?
discrete data
Hair colour is a type of discrete data because the values are distinct. You either have one hair colour or another! Continuous data covers a range, so each category is not separate but runs into the next.
Is heart rate continuous or discrete?
continuous
Variables such as heart rate, platelet count and respiration rate are in fact discrete yet are considered continuous because of large number of possible values. Only those variables which can take a small number of values, say, less than 10, are generally considered discrete.
Is sleeping time discrete or continuous?
Examples: Amount of sleep is a variable. 3, 5, 9 hours of sleep are different values for that variable. Variables can be continuous or discrete….Frequency distribution table:
| Score (X) | Frequency (f) |
