Study Notes
Correlation and Regression
- Correlation is used to denote an association between two quantitative variables, assuming a linear relationship, where one variable increases or decreases by a fixed amount for a unit increase or decrease in the other.
- In everyday life, correlation is used to describe an association, such as the connection between foggy days and attacks of wheeziness.
- Regression involves estimating the best straight line to summarize the association between two variables.
Correlation Coefficient
- The correlation coefficient, denoted by r, measures the degree of association between two variables.
- The correlation coefficient is sometimes called Pearson's correlation coefficient after its originator.
- It is a measure of linear association between two variables.
