what are outliers and influential points in graphs dealing with data
Answered by Damon
An outlier is a point that lies far away from a line or curve through the rest of the data. The chances are that it is a mistake and you might well throw it out.
An influential point is a point that is not close to the other data points in x coordinate but it might be close to a line or curve through the rest of the data.
On the other hand, an influential point might not lie close to a line or curve through the rest of the data, and therefore an influential point might also be an outlier.

The number of arrests, y, of a city over a period of time, x, is graphed on a rectangular coordinate system. Write a paragraph describing your interpretation when the slope is positive, zero, and negative. If you were buying a home in this particular city, which slope would be most attractive to you and why?
