[K12OSN] Request for suggestions regarding comprehensive statistics on a large survey

Wow, I hope you had a chance to design the study and examine assumptions and sampling first before collecting data. That makes the statistical analysis easier.

That being said, I have to admit that I too have been in situations where the data were collected first before thinking about the underlying statistical models. 

Without knowing anything about your data, I'd imagine that an analysis of variance (ANOVA) maybe couple with factor analysis may be the best approach. You can get the tools to do these kinds of analyses with packages like SAS, SPSS or Statgraphics, among the ones that I've used in the past.

Instead of a spreadsheet, you may want to consider storing your data into some kind of DBMS. Filemaker is a nice one and MS Access can suffice too. Storing the data in this form can make the retrieval process easier when it comes time to feeding these data into a statistics package.

I hope this helps some.
