A data point that "lies" significantly "outside" Possible outlier
the general trend in a set of data; it could
prove to be a true outlier that should be
removed or it could be legitimate data that
should remain in the data set
With a strong r2 is it reasonable to remove yes

Given that healthcare costs are going up in Concave down would be preferable for healthcare costs, as
the United States, would it be preferable for that would mean healthcare costs are going up slower and
healthcare costs over time to be concave slower.

Decreasing slower and slower is actually a
concave-up situation. Further health care
costs are increasing, not decreasing.
