Observation consists of receiving knowledge of the outside world through our senses, or recording information using scientific tools and instruments. Any data recorded during an experiment can be called an observation. A scientific process or scientific method requires observations of nature and formulating and testing the hypothesis.
Observation is what one sees, inference is an assumption of what one has seen. Observation can be said to be a factual description, and inference is an explanation to the collected data. It's not a guess. If an observation can be termed as a close watch of the world around you through the senses, then inference can be termed as an interpretation of facts that has been observed. Teachers can start out providing simple observations: 1  Observation: The grass on the playground is wet.
