Question

if you asked people to give their age and you collected it as <5, 6-10, 11-15, 16- 20, 21-25, 26 and older, what type of variable is this?

Answer 1

If we asked people to give their age and you collected it as <5, 6-10, 11-15, 16- 20, 21-25, 26, and older, it is a type of Discrete variable.

What is a Discrete variable?

• A discrete variable is one whose value can be determined by counting.
• A continuous variable is one whose value can be determined through measurement.
• A random variable is one whose value is the numerical result of a random phenomenon.
• The possible values of a discrete random variable X are countable.
• As an example, It is a type of Discrete variable if we asked people their age and you collected it as 5, 6, 10, 11, 15, 16, 20, 21, 25, 26, and older.
• There are two types of quantitative variables: discrete variables and continuous variables.
• Counts are represented by discrete variables (e.g. the number of objects in a collection).
• Continuous variables represent quantifiable quantities (e.g. water volume or weight).

Therefore, if we asked people to give their age and you collected it as <5, 6-10, 11-15, 16- 20, 21-25, 26, and older, it is a type of Discrete variable.
