Does anyone here use the SPSS statistical software package? I am currently performing an ANOVA analysis for house type (detached, semi, flats and terraced) against occupancy (range 1-6 people). Initial results show that there is a difference between the groups (detached have the most people, then semi, terraced and flats) but how do I get an r^2 value to show how well my model fits the observed data?

Is it possible to get an r^2 value from an ANOVA test? Specifically, does anyone know how to do this is SPSS?

Thanks
