an outlier is a number that does not fit in with the rest. for example in 2,3,5,9,7,8,5 and 16, the outlier is 16.

An outlyer is a datum point that does not fit in with the normal or usual distribution of data that one has observed for a sample set. In other words, it's a piece of data that just doesn't fit with what is expected. It can either be an anomaly or data collection error.
For example, if every year in Phoenix there are between 1/4" and 5" of rain, and one year there is a record of 22" of rain, we would call that datum an outlier. Maybe we would include it in an analysis, maybe not, depending on what we were trying to show and how accurate we believe the reading to be.

In statistics, an outlier is a single observation "far away" from the rest of the data.
In most samplings of data, some data points will be further away from their expected values than what is deemed reasonable.

In statistics when you have a whole bunch of numbers between say 5 and 30 and there's this one annoying 50 sitting there. Outlier.
