In statistics, it is the lowest kind of measure. Qualitative measures can assign observations to categories but there is no objective ordering of these categories - at least, not in the context of the study. Common examples are gender, race, religion, colour (for a car).
Qualitative means descriptive data and verbals
Bad things. When your blood is circulating too hot, it affects everything. Your internal organs are stressed, as well as your brain. (which is why it's dangerous to have a high fever for very long) Your muscles start burning anything they can to function instead of oxygen, which results in them producing lactic acid. (that's why after you exercise you feel that burn) The body uses up all the liquids it can, taking them from needed functions. It's a dangerous state to be in--for short.
Some of the bad things are: dizzyness,headache.hurts to do anything,and you don't even want to open your eyes. If you do overheat just sit or lie down until you feel better. when you do get up you will feel a little dizzy still but don't worry that's normal.
A nucleus of an atom can be compared to the sun of a solar system because the nucleus, like the sun, is the largest part of an atom and its electrons orbit around it, much like planets in a solar system. Atoms can also gain or lose electrons similarly to how stars can gain or lose planets.
On the internet, SEM stands for "Search Engine Marketing".
In it's most basic form, SEM includes any type of advertising that takes place within a search engine, hence the phrase "search engine" marketing. Search engine marketing may assume any form within a search engine but the two most common forms include SEO and PPC.
SEO refers to "Search Engine Optimization" and is the name give to the methods and process of improving a sites rank within it's organic or natural listings. SEM includes SEO but is not limited purely to SEO.
PPC stands for "pay per click" and refers to the paid advertisements as they appear within a search engine. For example, in Google, the paid ads appear under the label "sponsored links". SEM includes PPC but is not limited purely to PPC.
In biology SEM stands for "Scanning Electron Microscope".
The SEM is a particular type of microscope that produces images on a monitor by scanning the specimen with a high energy beam of electrons. The SEM is far superior to the light microscope in that a SEM can magnify a sample up to 2,000,000 times its size where as a light microscope can go as high as 2000 magnification. Thus, a SEM allows you to see small things such as smaller viruses that would otherwise never be seen by a light microscope.
This type of electron microscope only captures the surface image of the specimen It is done by plating the specimen with a type of metallic ion that then the high resolution beams can detect the image and reproduce/ capture it.
In Science SEM has long meant "standard error of the mean" a statistical term that relates the spread of numbers around the average for those numbers.
