What else can I help you with?
Why is it preferable to draw a line of best fit rather than to connect the dots?
show a trend
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
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.
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.
What is the purpose of a best fit line?
The best fit line is basically the average of a graph; it represents where, when, etc. the majority of the event occurred.
Is it ALWAYS possible to draw a line or curve of best fit in a scatter plot?
yes
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.

How do you draw a best fit line?
As I know, it is like this... From the bottom point you have put, you connect it till the end point with just a straight line. You don't follow every points as that isn't line of best fit. Hope that did help! :)
Does the trend line always pass through every point on a scatter plot?
No. When you draw a best line of fit on the scattered plot, the line would not be straight.
When should I draw a smooth curve a best fit line or only join the plots (I am especially thinking about Biology for that last one)?
You should use a curve if the scatter plot shows a clear curving shape. Otherwise draw a straight line. But a line of best fit should never zigzag from point to point.
How do you make a best fit line graph?
You want to draw a line through your plotted points and try to get equal amounts on either side.
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.
Are the points connected in a scatter plot?
No, you draw a general line through the middle of the points.(A line of 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.
