Average - the numerical result obtained by dividing the sum of two or more quantities by the number of quantities; an arithmetical mean.
Mean - halfway between extremes; in a middle or intermediate position...a number between the smallest and largest values of a set of quantities, obtained by some prescribed method.
Median: »davidmlane.com/hyperstat/A27533.html
The median is the middle of a distribution: half the scores are above the median and half are below the median. The median is less sensitive to extreme scores than the mean and this makes it a better measure than the mean for highly skewed distributions. |

| You left out the other measure of central tendency: the mode. In statistics, the mode is the value that occurs the most frequently in a data set or a probability distribution. |

Beaverton, OR | Yeah but everybody still thinks of average being the only relevant one. Ask random people on the street what the mode of a given set of numbers is and they'll likely either quote the average or stare at you all confused. |

There's a small hairy German man screaming something about "standard deviations" in my brain but I think that's just a flashback to statistics class in college.... the alcohol makes him go away. |
