The differences are matters of degree. That is, there's no special technique that makes an observation "scientific." Probably the best way to distinguish a scientific observation is to see how that observation is described. The more objective the description, the more scientific the observation. For example, whereas an ordinary description of an auto accident might read, "The blue car came out of nowhere, weaving drunkenly, and smashed into the van," a "scientific" description might look more like this: "The blue car collided with the van, striking the latter in the left rear panel as the van was approximately halfway through the intersection."
A non-numerical description is a qualitative observation. It uses words to describe qualities or characteristics of an object, event, or phenomenon instead of numerical data.

Quantitative observation means that your description of what you observedincludes a definite number that you measured.For example:"I saw a really big guy." is not a quantitative observation."I saw a guy who is 8 feet tall." is a quantitative observation.
