What is the difference between continuous and 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 discrete random variable X has a countable number of possible values.
How do you know if data is discrete or continuous?
Discrete data is a numerical type of data that includes whole, concrete numbers with specific and fixed data values determined by counting. Continuous data includes complex numbers and varying data values that are measured over a specific time interval.
What is discrete data example?
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.
Is age discrete or continuous?
Age is, technically, continuous and ratio. A person’s age does, after all, have a meaningful zero point (birth) and is continuous if you measure it precisely enough. It is meaningful to say that someone (or something) is 7.28 year old.
Is gender a discrete or continuous variable?
On purpose, I made it sound distinct that a variable is either 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 |

Is eye color a discrete or continuous variable?
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 height a discrete variable?
A discrete variable is one that cannot take on all values within the limits of the 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.
Is blood type discrete or continuous?
Blood type is not a discrete random variable because it is categorical. Continuous random variables have numeric values that can be any number in an interval. For example, the (exact) weight of a person is a continuous random variable. Foot length is also a continuous random variable.
Is blood group continuous or discontinuous?
Human blood group is an example of discontinuous variation. In the ABO blood group system, only four blood groups are possible (A, B, AB or O). There are no values in between, so this is discontinuous variation.
Is foot size continuous or discontinuous?
4) Shoe size is an example of discontinuous variation whereas foot length is continuous variation.
Is leaf size continuous or discontinuous?
Examples of continuous variation include height, weight, heart rate, finger length, leaf length etc. Examples of discontinuous variations include tongue rolling, finger prints, eye color and blood groups.
Is height continuous or discrete?
For example, height, weight, and time are typically assumed to be continuous. Of course, any measurement of these variables will be finitely accurate and in some sense discrete.
Is Money continuous or discrete?
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.
Is cost a discrete or continuous variable?
Cost is technically a continuous variable. Consider that something can cost $0.01 – infinity.
Is yes or no discrete or continuous?
Discrete data can be further sub-divided into three categories: binary, nominal and ordinal. Binary Data: A binary data only takes on two possible values. For example, lamp is on or lamp is off, answer is true or false, 0 or 1, yes or no etc. These five responses are ordered so this would be an example of ordinal data.
Is hours of sleep discrete or continuous?
Amount of sleep is a variable. 3, 5, 9 hours of sleep are different values for that variable. Variables can be continuous or discrete. Question: Are these variables discrete or continuous?
Frequency distribution table:
| Score (X) | Frequency (f) |
|---|---|
| (Hours) | (Number of people with this score) |
| 3 | 1 |
| 4 | 2 |
| 5 | 6 |
Is number of students discrete or continuous?
Discrete and Continuous Random Variables. The word discrete means countable. For example, the number of students in a class is countable, or discrete.
Is the price of a house discrete or continuous?
The question of whether house prices are an example of discrete or continuous data. Well I said they are continuous, since you can have any number of values between prices. My friend said they are discrete because the prices are based on a monetary system and money is discrete.
