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.
