I am reviewing an old dataset that I had originally analyzed in Statview (5.0.1), and re-ran some statistics in SPSS (v.16.0), with very different results. I am running ANOVA on food intake, using body mass as a covariate, with 3 experimental diet groups. The two programs produce different sums of squares and utilize different degrees of freedom for the independent variables, thus producing very different p-values.
Has anyone working with these two programs run into anything similar? BTW, if I run the ANOVA with no covariate, the sum of squares and F-statistic and p-values match up between Statview and SPSS. Any ideas? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Mary Beth Voltura, Assistant Professor Department of Biological Sciences SUNY Cortland Cortland NY 13045 607-753-2713 marybeth.volt...@cortland.edu
