Teach it
Where it is taught, with guided notes, practice, homework, an exit ticket and an interactive Teacher Deck.
Examples
- A best-fit line through study data predicts grades.
- Draw the line so points are balanced above and below.
Key rule
The line of best fit models the trend, not every point.
Memory hook
Best-fit line = the trend line through the cloud.
