Answer :
Residuals are used to determine how the line of best fit relates to the data points
A residual value of -0.8 means, the point is 0.8 units above the line of best fit
The residual value is given as:
[tex]\mathbf{Residual = -0.8}[/tex]
When the residual value is less than 0 (i.e. negative), then the point is above the line of best fit.
So, the interpretation of a residual value of -0.8 is that, the point is 0.8 units above the line of best fit
