IVs are precentage of students eligible for fsm, percentage of non white students, total number students in each school, and whether not school classified as 'failing'.
The x axis is the dependent variable, and the y is standardised residuals. Is this correct? The books I've looked in say to put predicted value on x axis and residuals on y, but there isn't an option in SPSS. Or is that what my graph actually is (confused)?
Does this graph mean the regression is null? It's population level data if thet matters
Any help well appreciated.
