Best Answer

A simple method involves cutting a rubber band. Then the rubber band straight line is stretched over the scatter diagram and moved about until you feel that 50 % of your data is on one side of the temporary line and the other 50 % is on the other side of the line.

Often the data is grouped such that a lot of points fall on the imaginary line of the rubber band and only a few oddballs are positioned well away from the line.

We think of this method as the " Best Fit " method, using your judgment to decide the best fitting trend line.

line graph scatter graph

First make a table of values, then draw axes and label them appropriately Then plot points carefully, and join with a curve or line (the particular way of drawing the line depends on the type of graph: scientific, scatter or mathematical.) Scientific graphs have values resulting from experiments. You draw a curve that follows the general trend of the points. (And passes within experimental error of the points) Scatter graphs are plotted with a straight line of best fit. Mathematical graphs should be joined with curves that pass exactly through the points.

No. When you draw a best line of fit on the scattered plot, the line would not be straight.

No. Generally speaking, a trend graph has time on the horizontal axis. That is not always the case with line graphs.

The trend line for a scatter plot is a line that best captures the nature of the relationship between two variables. It may or may not be straight.
