Scatter Plots & Lines of Best Fit To graph and interpret pts on a scatter plot To draw & write equations of best fit lines

Scatter Plots Graph used to determine if there is a relationship between 2 sets of data + Correlation - Correlation No Correlation Very strong + or - : determined by being more in linear form

Example Grades vs. Shoe Size Grades Shoe Size

Line of best fit Used to make predictions and represent the data in a scatter plot Fits most of the data With the line of best fit, try to represent all the points. To write an equation of a line of best fit, use 2 pts and go w/ what you know.
