In mathematics, an average is a measure of the "middle" or "typical" value of a data set.[citation needed] It is thus a measure of central tendency.
In the most common case, the data set is a list of numbers. The average of a list of numbers is a single number intended to typify the numbers in the list. If all the numbers in the list are the same, then this number should be used. If the numbers are not the same, the average is calculated by combining the numbers from the list in a specific way and computing a single number as being the average of the list.
Many different descriptive statistics can be chosen as a measure of the central tendency of the data items. These include the arithmetic mean, the median, and the mode. Other statistics, such as the standard deviation and the range, are called measures of spread and describe how spread out the data is.
The most common statistic is the arithmetic mean, but depending on the nature of the data other types of central tendency may be more appropriate. For example, the median is used most often when the distribution of the values is skewed with a small number of very high or low values, as seen with house prices or incomes. It is also used when extreme values are likely to be anomalous or less reliable than the other values (e.g. as a result of measurement error), because the median takes less account of extreme values than the mean does.
Welcome to where it all begins,
a place that's full,
of good luck and coincedents,
My condition is cool
but that's not the state i'm in,
i lean my head against you now
let the emptyness in.
Win or lose, i couldn't care less but i do
twentyfive years
and i'm still waitin for my cue
explain my part
in this game of hearts
i think i've just fell through
i lean my head against the wall
waitin' for my call...
won't you follow my down
cuz i can't send my ticket for another round
we're just average
and we're boring as hell
runnin' in circles to find ourselves
we're average
and we're boring as hell
we keep runnin' in circles to find our way
and we all have our time...
I saw you smilin'
in Regent's Park in the afternoon
With your hands in your pocket
next to the guys with all the balloons
explain my part
in this game of hearts
i think i just fell through
i wish i knew who you we're
so i can say...
won't you follow me down
cuz i can't send my ticket for another round
we're just average
and we're boring as hell
running in circles to find ourselves
we're average
and we're boring as hell
we keep runnin' in circles to find a way
