I need to do a two-way anova in spss, but I dont know where to do it.
Any help would be appreciated.
There are several SPSS tutorials on the web. A google search for SPSSQuote:> I need to do a two-way anova in spss, but I dont know where to do it.

Search for "SPSS tutorials" on that page.
In a two-way ANOVA, cell means model (with interaction), was wondering how one
can test for a linear trend on one factor within separate levels of the second factor ?
Given factor A, 2 levels, and B, 3 levels, the cell means model for a dependent
variable Y can be calculated as follows:
CLASS A B;
MODEL Y = A B A*B;
LSMEANS A B A*B;
In the univariate ANOVA, a linear trend for factor B can be tested as follows:
MODEL Y = B;
CONTRAST "Linear trend" B -1 0 1;
How, if possible, can I test for a linear trend in B within separate levels of factor A,
given the cell means model ?
Some might find the syntax for CONTRAST statements in interaction models a piece
of cake, but I unfortunately do not belong to that "lucky" group....
