Final answer:
The number of people attending a performance represents quantitative discrete data, as attendees can only be counted in whole numbers.
Step-by-step explanation:
The number of people attending a performance is an example of quantitative discrete data.
This is because the number of attendees can only be whole numbers; you cannot have a fraction of a person attending.
In contrast, continuous data often include measurements that can have fractional values, such as weights or times.
An example of continuous data might include the duration of the performance in hours and minutes, which could indeed have decimal values.
When considering the number of tickets sold to a concert, this too would be considered as quantitative discrete data, as tickets are sold in whole units and cannot be divided into fractions.
