What is discrete numbers example?
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.
What are two examples of continuous variables?
In general, quantities such as pressure, height, mass, weight, density, volume, temperature, and distance are examples of continuous random variables.
Is age discrete or continuous?
We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous. However, in everyday appliances, all values under 6 years and above 5 years are called 5 years old. So we use age usually as a discrete variable.
Is gender a discrete or continuous variable?
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 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 blood type continuous or discrete?
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 IQ discrete or continuous?
When you’re ready, check your answer below. IQ – discrete. IQ scores are always integers – 100, 110, 180, etc. ACT – discrete.
What are the similarities and differences between discrete and continuous random 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 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 the difference between discrete and continuous variables?
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 can take on almost any numeric value and can be meaningfully divided into smaller increments, including fractional and decimal values. You often measure a continuous variable on a scale. For example, when you measure height, weight, and temperature, you have continuous data.
What are the two types of discrete variables?
Discretely measured responses can be:
- Nominal (unordered) variables, e.g., gender, ethnic background, religious or political affiliation.
- Ordinal (ordered) variables, e.g., grade levels, income levels, school grades.
- Discrete interval variables with only a few values, e.g., number of times married.
Which are continuous variables?
Continuous variables can take on an unlimited number of values between the lowest and highest points of measurement. Continuous variables include such things as speed and distance. Discrete data are associated with a limited number of possible values.
What is discrete and continuous value?
Discrete data is information that can only take certain values. Continuous data is data that can take any value. Height, weight, temperature and length are all examples of continuous data.
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 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.
What are examples of quantitative variables?
Examples of Quantitative Variables / Numeric 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).
Is IQ a quantitative variable?
Other examples of continuous quantitative variables are temperature, age, height, weight and time. Other examples of discrete quantitative variables are the number of legs on an animal, number of siblings, ACT scores, IQ scores, and shoe size.
What is a quantitative variable?
Quantitative Variables – Variables whose values result from counting or measuring something. Examples: height, weight, time in the 100 yard dash, number of items sold to a shopper. Qualitative Variables – Variables that are not measurement variables. Their values do not result from measuring or counting.
Is income a quantitative variable?
(*) Household size, monthly income and number of computers — these are quantitative variables. Income is a continuous variable. Household size and number of computers are discrete variables.
Is heart rate a discrete or continuous variable?
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 ZIP code discrete or continuous?
continuous Discrete Attribute Has only a finite or countably infinite set of values Examples from text: zip codes, counts, or the set of words in a collection of documents, binary data.
Is a Social Security number discrete or continuous?
Some variables, such as social security numbers and zip codes, take numerical values, but are not quantitative: They are qualitative or categorical variables.
Is a phone number discrete or continuous?
It is also a discrete variable because one can simply count the number of phone calls made on a cell phone in any given day. The possible numbers are only integers such as 0, 1, 2, , 50, etc. (Some of you probably make a lot of cell phone calls.)
Is temperature discrete or continuous?
Temperature is continuous variable as it does have fractional value too. For example: Today’s temperature is 30. 5 degree Celsius, here 30.
