Curve Fitting (Grade 12 NSC Matric Mathematics): Flashcards

Identifying mathematical relationship between 2 variables

Data involving two variables

Direction & strength of relationships between variables

High values of one variable occur with high values of the other

Data points lie close to a recognisable pattern

Predicting values within the range of existing data

Predicting values beyond the range of existing data

Interpolation (within observed patterns)

Sum of squared distances between data points & line

$m$ is gradient (slope), $c$ is y-intercept
