Question
How would you interpret partial correlation ?
✓
Answer
- When the changes in the values of two correlated variables $X$ and $Y$ are in the same direction or in the opposite direction but not in the same proportion then the relation is said to be partial correlation.
- In such cases value of r is $0 < r < 1$ or $-1 < r < 0.$
- If the value of $|r|$ is near to one then we can say that correlation is near to perfect linear correlation and correlation is in very strong proportion.
- In such cases we can interpret the change in the value of one variable due to change in the value of other variable.
- If value of $|r|$ is near to $0$ then we can say that there is lack of linear correlation or strength of linear correlation is less.
- In such case we cannot interpret the change in the value of one variable due to the Change in the value of other variable.
