What is a line that comes as close as possible to data points as possible?
line of best fit.
What are two reasons for all the points not been on a line of best fit?
A line of best fit is used to create an image of the overall correlation between two factors on a scatter graph (showing the general shape of the graph). As a line of best fit should be either a straight line or a smooth curve, the line visiting every point would be impossible to retain this shape (as the experimental results will likely not be identical to the theoretic ones). Also, a line of best fit can be used to highlight anomalous results, so the whole point of it would be destroyed if every point was visited anyway.
A smooth line that reflects the general pattern in a graph?
The line that reflects the general pattern of a graph is called a trend line.
Explain how you could use your best fit line to find the weight of a mass without hanging it from a spring scale?

Why should you draw a line of best fit when drawing a graph?
A best fit graph to some data is exactly that: it is a line which fits the data best according to some optimality criterion. There is a always a trade off in fitting a line to data: one can change the number of degrees of freedom of the underlying equation, which affects how close the line can get to the data points. With more degrees of freedom, the line can more closely approximate the data. This is not to say that more degrees of freedom are better: with too many degrees of freedom, one is merely fitting to the noise in the measurement of the data, and the line will predict subsequent data poorly, when both interpolating and extrapolating the existing data. This is an example of Occam's Razor: one must pick the simplest model which adequately fits the data.
What does a line of the best fit emphasize about the data?
it EMPHASiZES tHEE OVERAll tREND SHOWN By All tHEE DAtA tAkEN AS A WHOlE.
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.
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
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.
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.
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.
Which is the best equationof a line of best fit this scatterplot?
A straight line equation
