Thread: Linear regression for a survey - help needed

1. 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...

Kindest regards

2. Interesting problem.

It would be useful if you show us this questions and this 5 lickert scale points. Just to have an idea of the information you are gathering.

On the other hand, I dare say I think your problem is not a "statistical" one. In a regression analysis, you could relate any two variables (or more) and the test could be in favour or against your hypothesis. Having this in mind, you could use a variable as a "core" of "success". For example, you may state with non-statistical fundaments that success can be asociated to quantity of visits. Well, there you have a core variable and more visits mean more success. If you relate that variable to the factors you are measuring, a regression analysis will be easy to be set.

You may do a "discriminant analysis" to understand which factors are those which determine success from a set.

I do not know if I've been clear enough. My english is still quite bad.

Thank you very much for your help.

Well, here is a link to my survey so you can have a look at it.

Virtual Worlds_new

If you define success as the number of active user, the problem is I first of all might not have all the data, and secondly, I do not know which virtual world to take, as I want my research to be general so that it can determine the success factors for all the virtual worlds.

4. I've been on holidays (in Salta, Argentina). I'll review your poll from my work and then give you my not-profesional view.

I did some work related with cigarettes marks (brands) in the Argentinean smokers market. I had different marks. Smokers had to select one and answer a poll with questions like yours. We had a formula which gave points to each participant and then we ranked them with this points. For a very well-known american car manufacturer we did the same. In that cases, we compared among brands. It would be a first step to understand which factors are determinant for this virtual worlds in an ex-ante definition.

Do you have SPSS? If you have, you can do a Discriminant Analysis to understand which of the variables in your poll best explain your "rank" or a "quality" like: "3 hours per day of use", "1 hour per day", "less than 1 hour". You also can run a Cluster Analysis to understand which variables are related.

If you don't have, please send me an email and we could use another software called R ---> The R Project for Statistical Computing which is free and a powerful tool (like S-Plus) and you can use this tools.

Hope this helps.

Federico.

5. hi federico

I just sent you a private message.

I hope you can help me.
