What you'll learn

Use a scatterplot and its line of best fit to describe how two measured quantities are related and to predict a value, judging whether the prediction lies within the data
Read a point as one case carrying two measurements, with units, and explain why two points can share the same x-value
Describe a scatterplot's association using form, direction, and strength
State the criterion that makes a line the line of best fit, and explain why the line need not touch any data point
Read a predicted value off a line of best fit, and distinguish interpolation from extrapolation, explaining why an extrapolated prediction is weaker
Identify a point far from the overall pattern and predict which way it pulls the fitted line
