Warm Up
Which of the lines is the better fit for the data in each scatter plot? Be prepared to show your reasoning.
Compare your answer: Your answer may vary, but here is a sample.
The solid line is the better fit for the data since it goes through the middle of the data and follows the negative trend of the data with very few points a far distance from the line of best fit.
Compare your answer: Your answer may vary, but here is a sample.
The solid line is the better fit for the data since it goes through the middle of the data with approximately equal numbers of data points on either side of the line.
Compare your answer: Your answer may vary, but here is a sample.
The dashed line is the better fit for the data since it goes through the middle of the data with a slope that follows the trend of the data. The solid line has a lot of points above the line to start and a lot of points below the line at the end.
Compare your answer: Your answer may vary, but here is a sample.
The dashed line is the better fit for the data since it goes through the middle of the data, follows the trend of the data, and has a similar number of points on each side that are not far from the line. The solid line fits the first and last point perfectly, but most of the data are above the line.
