description means to describe something
A physical description is the description of the physical properties (what you can see) of an object. For example, a rough physical description of the moon would be: round, white, big, bright, looks like a face.
In science a inference is a attempt to explain a observation
That is the correct spelling of "observance" (a commemoration).
"Brief description of yourself" is asking for a small description of you. You could include your name, age, likes and dislikes. A few sentences so that others can learn something about you is sufficient.
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.
It will enable you to monitor how well the child is developing and how he behaves in a social environment with his peers.
qualitative
microscope
casual observation
research that includes interviews and informal conversations
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."
Facts
a row means an observation if there are many rows.
A scientific description requires accurate measurement and observation, with as much detail as the scientist can manage. Sometimes it is the small details which are the most revealing.
25 x36 = 900 13 x 32 = 416 13 x 40 = 520 ----- 936 936-900 = 36 (13th observation)
Observation is an act of investigatingor studying through close examination or systematic approach. It is done by the use of the five senses. On the other hand, description is the act of giving an account or mental image of what you have observed through the use of adjectives.
