What's the difference between trends and regression lines?

Click For Summary
SUMMARY

The discussion clarifies that a regression line is a mathematical construct used to minimize the residual sum of squares, while a trend represents an interpretation of data that is ideally backed by a plausible cause. It distinguishes between linear and non-linear regression lines, emphasizing their role in statistical analysis. Understanding these concepts is crucial for accurate data interpretation and modeling.

What's the difference between trends and regression lines (linear and non-linear) which minimize the residual sum of squares?
 
Physics news on Phys.org
A regression line is a mathematical entity. A trend is a possible interpretation, preferably supported by some feasible cause.
