Due Monday, April 23. Now calculate residuals and the sum of the residuals to find the best line to fit the data. Plot the five data points along with each of the equations on the TI-83. Notice where the lines pass through the data points and where they pass far from the data points.
Linear regression assumes that the function is linear.
Another name for linear regression is least squares or least squares best-fit line. Snowmelt as a function of temperature. Use the same five data points and the TI-83 to perform linear regression. The following graph was created using Excel. A trendline in Excel means a regression line.
