Visualisation of covariance

[Marco Venus]

Dear list,

Is there a way to visualise covariance of certain variables in a sort of
diagram/graph with circles that show a degree of overlap? If so, how will I
be able to design such a graph in SPSS or another programme?

Cheers,

Marco

Look at the homogeneity of slopes

If an interaction between a covariate and a factor in the model is
significant, it indicates that the slopes relating the covariate to the
dependent variable vary across groups.
