Regression and Residual

What is Regression?
Regression line helps us to predict change in Y for a change in X.

From previous example (https://mylearningcafe.blogspot.com/2019/12/correlation.html), we can see if we can determine the value of Y for a value of X.





What is Residual?
Residual tells us the error in the prediction (Actual value - predicted value).
We can see the difference from above known values.
