Download Solution PDFThe correct answer is Co-efficient of correlation is strong and positive.
Key PointsIf the coefficient of correlation is having a value of more than +0.75, the relationship between the variables will be strong.
In simple linear regression analysis, the coefficient of correlation (or correlation coefficient) is a statistic which indicates an association between the independent variable and the dependent variable. The coefficient of correlation is represented by "r" and it has a range of -1.00 to +1.00.Additional InformationA correlation coefficient is a number between -1 and 1 that tells you the strength and direction of a relationship between variables. In other words, it reflects how similar the measurements of two or more variables are across a dataset.
| Correlation coefficient value | Correlation type | Meaning |
| 1 | Perfect positive correlation | When one variable changes, the other variables change in the same direction. |
| 0 | Zero correlation | There is no relationship between the variables. |
| -1 | Perfect negative correlation | When one variable changes, the other variables change in the opposite direction. |
