The correlation values 1 and -1 represent a perfect linear relationship between the two variables x and y.
Step to Step explanation:
- To represent perfect linear relationship between two variables the correlation values should be 1 and -1.
- When correlation value is equal to 1 it represent the positive linear relationship between two variables x and y.
- Slope of the correlation value positive 1 indicates the increasing slope.
- When correlation value is equal to -1 it represent the negative linear relationship between two variables x and y.
- Slope of the correlation value negative 1 indicates the decreasing slope.
Therefore, the perfect linear relationship between two variables x and y is given correlation value 1 and -1.
