Detailed explanation-1: -Discrete data is a count that can’t be made more precise. Typically it involves integers. For instance, the number of children (or adults, or pets) in your family is discrete data, because you are counting whole, indivisible entities: you can’t have 2.5 kids, or 1.3 pets.
Detailed explanation-2: -Variables such as number of children in a household are called discrete variables since the possible scores are discrete points on the scale. For example, a household could have three children or six children, but not 4.53 children.
Detailed explanation-3: -It is discrete as if it was continuous it would mean you can have 225 children, which isn’t possible. With discrete, it means you only have 0, 1, 2, 3, etc.
Detailed explanation-4: -The number of animals in a zoo is continuous data because the number of animals varies yearly depending on the reproduction of new animals or the arrival of new animals. The result of the rolling is a dice is 1, 2, 3, 4, 5, 6, 7, and 8. Therefore this is discrete data.
