The default for obtaining sums and means in SPSS is to work them out only for cases with complete data.
To sum over cases, with at least x complete variable values in SPSS, we use the function, sum.x. Similarly to obtain the mean for cases, with at least x complete variable values, we use mean.x. e.g.
compute scoresum = sum.3(a,b,c). compute scoremn = mean.2(a,b,c). exe.
scoresum will return missing for cases with <3 non-missing values. Ie any non-missing a, b and c. scoremn will return missing for cases with <2 non-missing values, ie having two or three missing values of any of variables a or b or c.
