Final answer:
An example of A. an application using streaming data is an application evaluating sensor data in real-time. This involves processing and analyzing data continuously as it is generated, unlike storing data in databases or one-time data transfers.
Step-by-step explanation:
The correct statement that describes an example of an application using streaming data is A. An application evaluating sensor data in real-time. Streaming data involves a continuous flow of data, which is processed and analyzed as it's being generated, without waiting for the entire data set to be available. Examples of streaming data often include applications for real-time analytics, monitoring, and interactive dashboards. Large-scale web applications, databases, or one-time data transfers may manage large volumes of data, but they do not necessarily involve the continuous and real-time nature of streaming data.
In the context of data types and sampling:
- For the example of the number of tickets sold to a concert, this would be a quantitative discrete datum, as it represents countable units that can't be subdivided meaningfully.
- An application like a computer that can store and perform calculations on large data sets could potentially deal with any type of data, depending on the calculations it's programmed to perform.
- A data set comprising a large amount of experimental results on molecules and their motion would likely involve quantitative continuous data, representing measurements that can be infinitely subdivided, such as time or distance.
