Alg 1 Lesson 5.16 Linear Regression with a Graphing Calculator | Correlation Coefficient Explained

In this Algebra 1 lesson, students learn linear regression, how to find the line of best fit, and how to interpret the correlation coefficient (r) using a graphing calculator. This video walks through the guided notes page of a linear regression lesson, explaining how to enter data, compute the line of best fit, and analyze the strength and direction of relationships between variables. In this lesson, you will learn how to: ✔ Use a TI-84 or Desmos to calculate linear regression ✔ Find the equation of the line of best fit ✔ Interpret the correlation coefficient (r) ✔ Identify strong, weak, positive, and negative correlations ✔ Use regression equations to make predictions from real-world data We walk through step-by-step examples, including: 📌 Modeling the growth of a puppy over time 📌 Predicting car value depreciation 📌 Understanding how regression models real-world relationships This video is perfect for: • Algebra 1 students • 8th grade math data analysis units • Scatter plots and regression lessons • Graphing calculator tutorials 🎯 Learning Targets • I can use a graphing calculator to find the linear regression of a set of data. • I can use the correlation coefficient to indicate the relationship between two variables. 📥 Want the guided notes + worksheets + answer key that go with this lesson? 👇 https://www.teacherspayteachers.com/P...
