Question

which of the following is an example of a discrete relationship?
height of a person
purchasing tickets
weight
temperature

Explanation:

Discrete data consists of distinct, countable values that cannot be split into smaller increments. Purchasing tickets involves whole, countable numbers (you can buy 1, 2, 3 tickets, not a fraction of a ticket). In contrast, height, weight, and temperature are continuous data, as they can take any value within a range (e.g., 175.3 cm, 62.4 kg, 22.5°C).

Answer:

A. Purchasing tickets
