This is the 14th and last lesson in the Descriptive Statistics Unit. Students will calculate the slope and y-intercepts using statistics. They will calculate and interpret r^2 and the standard deviation of residuals. These lessons are set up to have the teacher lead the students through the note-taking process while incorporating examples for the students to try. The answer keys are provided. Homework will be added shortly at not additional cost to those who purchase before. I will also be making videos that take the student through the lesson for those that flip their classroom or for absent students. SMART notebook files are included for the teacher to fill in with the class.
