Q:

Data Analysis and sites

Which site is suitable to include questions on data analysis?
I'd like to post a question about theorical techniques that are applied to analyze the data and feedback that can be given after this analysis and how the subsequent analysis can be influenced by past analyzes.

A:

Cross Validated - Stack Exchange is suitable for questions on data analysis, as @Bart pointed out. Actually, they are quite common.
Just look at:
