How to determine the best fit line
WebThe line doesn't go on infinitely (I guess it is technically a line segment). If you plotted more and more points and the hours went up and up the line would just level off. Remember that this is data taken from the real world. It doesn't have the precision most math has. WebSep 26, 2024 · SumErrorSqb(m, b) = 28m + 6b − 62. Setting the two partials to zero and solving we see the partials are both zero when m = 2 and b = 1. One again, this method produces the same best fitting line. We can use the same methods with a larger problem. Example 6.4.4: Use the Solver Method on a Larger Data Set.
