Which of the following is an example of discrete data?

Discrete data is characterized by values that can only take on specific, separate values, often associated with counting. The correct example of discrete data from the options provided is the number of employees. This is because the number of employees can only be whole numbers; you cannot have a fraction of an employee. Therefore, the values are distinct and countable, making them discrete.

On the other hand, height of individuals, amount of rainfall, and temperature readings all represent continuous data. Continuous data can take on any value within a given range and can include fractions or decimals. For instance, height can be measured as 5.5 feet, rainfall can be 12.3 inches, and temperature can be 22.8 degrees Celsius, all allowing for an infinite number of potential values within specific limits.
