Study Notes

Key Contributions to Regression

Francis Galton is credited with coining the term 'regression'.
While studying the relationship between the heights of parents and their children, Galton described the data as exhibiting a tendency to 'regress' towards the mean height.

Historical Context of Linear Regression

Although Galton is well-known for the term, it is believed that Karl Pearson may have been the first to actually utilize linear regression techniques in his statistical work.

Graphing Calculator Capabilities

A graphing calculator can perform linear regression analysis on a given data set to determine the best-fitting linear model.
In addition to linear regression, graphing calculators can also perform polynomial regression, allowing for the modeling of more complex relationships between variables.
