Correlation analysis measures both the strength and direction of a linear relationship between two numerical variables. It quantifies the extent to which a change in one variable corresponds with a change in the other variable. This relationship is expressed as a correlation coefficient, which ranges from -1 to 1, with -1 indicating a strong negative relationship, 0 indicating no relationship, and 1 indicating a strong positive relationship. Correlation analysis is used in simple linear regression to assess the degree of association between the independent and dependent variables.
