In which type of observation is recording date and time especially useful?

Answer and explanation

Correct answer: In a phenomenon changing over time

For an observation of a phenomenon that changes over time, recording the date and time shows when the change occurred and how quickly it happened. This helps identify the sequence of events and a trend. For a one-time observation of a fixed colour, time is usually less important. Exam tip: Record date and time whenever an observation involves change or sequence.
