Difference Between Discrete and Continuous Variable

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. Example: Let X represent the sum of two dice.

What is variable 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 the difference between discrete and continuous?

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 a variable distinguish between a discrete and continuous variable with example?

A variable that takes only whole number as its value is called discrete variable. These variables increase in jumps or in complete numbers. For example- Number of people in a family, number of students in a class, etc. A variable that can take any value, within a reasonable limit is called a continuous variable.

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 gender a discrete variable?

Discrete data: when the variable is restricted to specific defined values. For example, "male" or "female" are categorical discrete data values.

Is age continuous or discrete?

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.

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.

How do you tell if a graph is discrete or continuous?

When figuring out if a graph is continuous or discrete we see if all the points are connected. If the line is connected between the start and the end, we say the graph is continuous. If the points are not connected it is discrete.

Is profit a discrete or continuous variable?

The number of each type of job completed by a company each month, the number of employees required for work each day or the profit a business makes each month are all examples of discrete 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.

What are the types of continuous variables?

There are two types of continuous variables namely interval and ratio variables.

What is one example of a continuous variable?

A variable is said to be continuous if it can assume an infinite number of real values. Examples of a continuous variable are distance, age and temperature.
