A line of best fit allows one to track the trend in their data. It is particularly helpful when one's data is scattered.
A best-fit line is the straight line which most accurately represents a set of data/points. It is defined as the line that is the smallest average distance from the data/points. Refer to the related links for an illustration of a best fit line.
The line of best fit is the best possible answer you can get from raw data. They also can be used to make predictions.
What is the difference between a trend line and a line of best fit
The straight line that best fits the data on a coordinate plane is the Line Of Best Fit.
Data points that are not close to the line of best fit are called outliers.
No, the best fit line need not go through any data point on a graph.
If most of them lie below the line, then that line isn't the best fit. The exact layout depends on what definition you use for "best fit", but any definition will produce a line that has roughly the same number of data points on each side of it.
