well because in the mean you have to add them and its different from the median and the mode
It depends on the data and sometimes on what you are trying to show with the data. All of them are indicators of central tendency and have different uses.
how many numbers your data is away from your mean
The answer depends on the type of data. The mean or median are useless if the data are qualitative (categoric): only the mode is any use. The median is better than the mean is the data are very skewed.
Mathematical data can be best organized in numerical order. By doing this, statistics are more easily found, such as mean, median, and mode.
To answer this question I will use an example. Data set: 10, 20, 30, 40, 50. First find the sum of all the numbers...so 10+20+30+40+50= 150. Then you take the sum (150) and divide it by the number of numbers in the data set. So 150 divided by 5 (the number of numbers in this data set) = 30. 30= the mean of the above data set. Finding the mean is pretty simple. :)

to represent the data givin, or you have found
how many numbers your data is away from your mean
If the set of data are represented by a letter, then the mean is represented by that letter with a bar across its top.
Graphs, Tables, or Charts that represent what you tested
It is used to represent one of the two possible outcomes of tossing a coin.
Information is stored in data, which is a collection of information. Strictly speaking, a datum (singular form of data) is a single unit of information.

A line graph is often used to represent a set of data values in which a quantity varies with time
of course not... since lower did't mean lowest><
If you explain what you mean by "Article 8" I'll do my best to help.
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.
