Creating Weighted and Unweighted Averages in SPSS

[@abbassbzeih4827]

Why you choose to multiply by .2? Is their any rule for calculating the weighted average? Thank you.

Todd, how do you create weighted averages for a time block (a 3 hour interval in which feelings and imagination were measured)? Do you have to create a specific variable named time block?

Is it possible percentage of unweighted data is larger than percentage of weighted data?

I have survey data that is over and under representative on multiple predictor variables. Over sample of women, under sample of men, over sample of white and under sample of black, class, education and so on. Can you provide a link, a reference or directions how to weight these cases in SPSS?
