It is very useful and interesting to be able to enter data for two variables, graph those points in a scatter plot, and then generate a line of best fit through those points. From the line of best fit, it is fairly simple to generate a linear equation. A line of best fit is drawn through a scatterplot to find the direction of an association between two variables. This line of best fit can then be used to make predictions.

What is the difference between a trend line and a line of best fit and how are they useful in analyzing data?
What is the difference between a trend line and a line of best fit
What is a line of best fit on a line graph?
The line that minimized the sum of the squares of the diffences of each point from the line is the line of best fit.
What is a best fit line on a graph?
When points are marked on a graph, a line is often drawn across the dots plotted. A line of best fit is a straight line that goes through as many of such points as possible.
A trend line on a graph is always the same as the line of best fit?
No.
Does a best fit line connect all of the data points in a line graph?
yes
What is the difference between a trend line and a line of best fit and how are they useful in analyzing data?
What is the difference between a trend line and a line of best fit
A best line fit may not be very useful between these two variables since the data points on the graph are?
Not linearly related.
Is the best fit line the same as the line of best fit?
Yes but phrased differently
What is a line of best fit on a line graph?
The line that minimized the sum of the squares of the diffences of each point from the line is the line of best fit.
What is a line that is not a line but is almost a line?
A line of best-fit.
Why does best fit line does not touch all data points?
Because the "best fit" line is usually required to be a straight line, but the data points are not all on one straight line. (If they were, then the best-fit line would be a real no-brainer.)
Does the line of best fit have to start from the origin?
The line of best fit does not have to pass through the 0 (origin) and rarely does
What is the process of finding line of best fit called?
Finding the line of best fit is called linear regression.
What is a best-fit-line?
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.
How do you find a line of best fit from scatter plot?
The line of best fit is simply the line that shows the general direction of the graph. The trick is to make the line go through as many points on the graph as possible. Some scatter plots have no line of best fit.
What is an example of a best fit line?
Check out the related links section below to see an example of a line of best fit.
Does the line of best fit have to be straight?
Not necessarily. Often it is, but the line of best fit is simply an equation that closely matches the results. Therefore any line could be a line of best fit, linear, quadradic, or even cubic! The sky (and the results) are the limit.
