Linear regression for a survey - help needed

Hi everyone,

For my master thesis, I am trying to prepare a survey on the general key success factors for virtual worlds.

My hypotheses are that user generated content, community management, etc. all those (independent) variables are key success factors. I asked questions on a 5 point lickert scale and then want to do a regression analysis in order to verify my hypotheses. However, I do not have any statement or question that measures the success of a virtual world. I cannot think of one and without it I cannot do my linear regression, right?

How can I do that though? Sorry, I am very bad at maths...

Thank you very much for your help in advance.

Kindest regards
