Answer:
Each tag starts with a tag opener (a less than sign) and ends with a tag closer (a greater than sign).
Explanation:
Each tag starts with a tag opener (a less than sign) and ends with a tag closer (a greater than sign). Many tags have corresponding closing tags which identical except for a slash after the tag opener. (For example, the TITLE tag).
Some tags take parameters, called attributes. The attributes are given after the tag, separated by spaces. Certain attributes have an effect simply by their presence, others are followed by an equals sign and a value. (See the Anchor tag, for example). The names of tags and attributes are not case sensitive: they may be in lower, upper, or mixed case with exactly the same meaning. (In this document they are generally represented in upper case.)
Currently HTML documents are transmitted without the normal SGML framing tags, but if these are included parsers will ignore them.
Answer:
Validity is the degree to which the research measures what it has to measure. High validity = Proper Research Design.
Reliability is the measure to which research measurement techniques are free of error or mistakes. High realiability = Reasearchers know the sample fully understands the question asked.
Representativeness is the extent to which consumers in a study are similar to the larger group of interest. High representativeness = Sample is large and chosen in an unbiased way.
In the document...? Not sure what the question is.
