700 600 500 400 300 200 100 y=0.8774x + 154.61 R2 = 0.2284 50 100 150 200

Solution

The R² looks a little high but otherwise it looks OK. - R² is on the lower side

It is just 22.84% which shows a weak model.

Only 22.84% of the variance in the dependent variable is accounted by the independent variable
