WebIn this video, you will learn that a scatter plot is a graph in which the data is plotted as points on a coordinate grid, and note that a "best-fit line" can be drawn to determine the trend in the data. If the x-values increase as the y-values increase, the … WebA line that fits the data " best " will be one for which the n prediction errors — one for each observed data point — are as small as possible in some overall sense. One way to achieve this goal is to invoke the " least squares criterion ," which says to "minimize the sum of the squared prediction errors." That is:
WebThe regression line is sometimes called the "line of best fit" because it is the line that fits best when drawn through the points.
