Which is an example of discrete numerical data?

Discrete numerical data refers to data that can take on only specific, distinct values. These values are often counts of items or occurrences and can’t be sub-divided meaningfully.

In this context, the number of eggs in a carton serves as a perfect example of discrete numerical data because it can only assume whole number values. You can have 0, 1, 2, …, or 12 eggs, but you cannot have fractions of eggs like 2.5 or 3.7. Each value is countable and individual.

The other types of data given in the question—weight, height, and temperature—represent continuous numerical data, which can take on an infinite number of values within a given range. For example, a person’s weight can be anything from 60.0 kg to 60.1 kg to 60.01 kg, making it a continuous measure and thus not suitable for discrete classification.
