- Discussed how to describe an association--what should we include?
- Reviewed sketching scatterplot, finding r, R^2, and the equation of the line of best fit with our calculator (using the balance score/ankle range of motion context on our slide)
- Described the association between ankle range of motion and balance score (sample response)
- Discussed how to determine strength based on graph
- Discussed/took notes on correlation (r)
- Tuesday's Class:
- Notes on introductory vocab: scatterplot, explanatory variable, response variable
- Discussed lurking variables
- Introduced how to describe an association
