MERGE already exists as an alternate of this question. What is a line of best fit on a graph? The line could pass through some ofthe points, all of them, or none of them. A straight line is a shape defined by a set of two or more adjacent points all within the same one-dimensional space.

Does the line of best fit have to start from the origin? What is a best-fit line on a graph? A straight line which best describes the data on a scatter plot iscalled a "line of best fit". Best-fit line is used in a graph with a whole bunch of dots.

You want to draw a line through your plotted points and try to get equal amounts on either side. Would you like to make it the primary and merge this question into it? The result is a unique line that minimizes the total squared deviations, statistically termed the sum of squared errors.

What does a line of best fit allow you to do? What is a best-fit line as a math definition? A line of best fit is a straight line that goesthrough as many of such points as possible. It is "best" according to some user-specified criteria.

Well a straight line is something that you use in geometry and that is what you use to measure with. A straightline is one of those elementary geometric objects along with termslike point, angle, distance, etc that are assumed to exist, out ofwhich other figures may be constructed.

Using regression analysis, it finds the line that minimizes the amount of errors deviations - the sum of vertical distance of data points from the line. Of course you first have toestablish coordinate axes, which are all assumed to be straightlines.

What is a straight line? The line of best fit does not have to pass through the 0 origin and rarely does Why is a best fit line used?

The line of best fit is also known as the least square line. Algebracially you can define a straight line in terms of relationsamong the coordinates of each point.

Therefore any line could be a line of best fit, linear, quadradic, or even cubic! They also can be used to make predictions. So that approach seems shaky, too, lol.
