Show answer
Answer: D
Explanation
D. The number of phone calls that a call center receives in a day is an example of discrete data. Discrete data refers to data that can only take on specific, distinct values within a given range. In this case, the number of phone calls can only be a whole number, and cannot take on any other value. For example, the call center might receive 100 calls one day, and 105 calls the next day, but it could not receive 100.5 calls. In contrast, continuous data refers to data that can take on any value within a given range, such as measurements or temperatures. Categorical data refers to data that can be divided into categories or groups, and ordinal data refers to data that has a specific order or ranking.
