Which of the following data points would typically use an analogue input?

An analogue input refers to data that can take on a range of values, typically representing quantities that are continuous in nature. In the context of the given question, the temperature reading from a sensor is a prime example of this. Temperature does not consist of discrete values; rather, it can vary smoothly across a range (e.g., from -10°C to 50°C) and can be expressed in fractional units.

In contrast, the other data points provided are fundamentally different. The number of clicks on a website is a discrete count, reflecting individual actions that can only take integer values. The status of a light switch is binary, being either on or off, which does not require an analogue input as it represents a simple two-state system. A student's ID number is a unique identifier and consists of fixed, discrete characters, making it unsuitable for analogue input as well. These characteristics clearly distinguish temperature as the appropriate data point for an analogue input.
