Well in statistics you have data that is relativly normal. What is something OUTside of normal limits?

@e.mccormick help i ment 1. Do your data include any outliers? Explain how you know.

an outlier is any data that falls far away from other data. can also fall outside 3standard deviations if you are looking at a normal curve

13. e.mccormick

If you have a very small set of data it is hard to know if you have any outliers or not. The larger the set of data the easier it is to see if just a few values are strange. If you have 10 points and 1 does not follow the prediction path, well, perhaps you sampled just a small group that was not typical. But say you have 100 samples and only one does not follow the prediction path. It is more likely that one is an outlier (oddball, strange, bad reading, otherwise abnormal.)

thx @calliendra and @e.mccormick

Like calliendra said, outside $$\pm$$ three standard deviations. That is what I mean by prediction path.
