**Q1:** I am analysing a weighted survey, but I don't
have any special survey software. I have made sure that my weights
add to the achieved sample size and then I use a simple weighted
analysis in SPSS. Is this OK?

**Q2:** I see that in order to get the correct __design effects __
and __design factors __ in
SPSS I need to make sure my weights add to the population size. But I
don't have information on how large my population was. What should I do?

**Q3:** My superviser says I should use multi-level
modelling for clustered samples. Is this the same as analysing a
survey and setting a cluster option in a survey package? Is multi-level modelling better?

**Q4:** Obviously, it isn’t a good idea to use
weighting if your values vary enormously (for example, you have 96
males and four females, and you are attempting to balance it to
50:50. At what point would you say that it is
unadvisable to use weighting e.g. is it closer to a 75/25 or 50/50
spilt on values?
