# Definition of Outlier

An outlier is a data value that is very different from most of the other values in a data set. For example, if you have a list 18,19,17,16,1 and 35 of caterpillar weights in grams, the 1 gram and 35 gram weights are outliers.

In the picture, the red dot is a long way away from the rest of the data values, so it is an outlier.
