This is a whole lesson on regression lines and a look at coding as well. Coding comes up in three or four topics, but the bulk of my teaching on it is on the topic of making the variance easier. 18 slides + resources.
Specifically, this lesson is for teaching what a regression line is, to understand its links to real-life situations (excellent clear teaching slides and examples) and calculating a regression line for a given set, including using coding and a look at interpolation and extrapolation. The lesson does include a starter, lesson objectives, keywords, superb teaching slides and examples, exam questions with mark scheme and plenary.
