Re: Programmatically finding "significant" data points

How do I sort through this data and pull out these points of
significance?

Get a book on statistics. One idea is as follows. If you expect the points
to be centred around a single value, you can calculate the median or mean
of the points, calculate their standard deviation (aka spread), and remove
points which are more than N-times the standard deviation from the median.

Standard deviation was the first thought that jumped to my mind
too. However, that's not what the OP is after. He's seems to be looking for
points when the direction changes.
