What is discrete variable give example?

What is discrete variable give example?

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.

Which is discrete type of variable?

Discrete variables are numeric variables that have a countable number of values between any two values. A discrete variable is always numeric. For example, the number of customer complaints or the number of flaws or defects.

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

Is weight a discrete variable?

In general, quantities such as pressure, height, mass, weight, density, volume, temperature, and distance are examples of continuous random variables. ... This is not the case for discrete random variables, because between any two discrete values, there is an integer number (0, 1, 2, ...) of valid values.

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.

What are 5 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.

Are categories discrete?

Any subcategory of a discrete category is discrete. Also, a category is discrete if and only if all of its subcategories are full. The limit of any functor from a discrete category into another category is called a product, while the colimit is called a coproduct.

Is GPA discrete or continuous?

For example, the variable " the number of children" is discrete and the variable " GPA" is continuous. Since GPA can take an infinite number of possible values, for example interval 0.0 to 4.0.

Is BMI discrete or continuous?

Discrete quantitative variables can take on only a countable number of values, there are gaps between the possible choices. These are usually count variables of some kind. In our set above, blood pressure measurements and Body Mass Index (or BMI) would be clearly continuous.

Is kilogram discrete or continuous?

So it is obvious that weight is a continuous variable as it can be quantified with decimal precision;like 10.2 kg and 3.0122 kg. If we were to round it to an integer like 10 kg and 3 kg.
