The coefficient of correlation and the least squares line both describe the relationship between two interval variables.
Least Squares Line
A line that minimizes the sum of the squares of the vertical deviations from each data point to the line, often used in linear regression.
Interval Variables
Variables where the intervals between the values are interpretable, allowing for meaningful comparison and arithmetic operations.
- Execute calculations to determine the covariance and interpret the correlation coefficient between two variables.
- Ascertain and interpret the elements and the linear regression of least squares in bi-variate statistical examination.
