Currently I'm trying to find out how to measure the user experience concerning web applications. I've already collected metrics like response time, device type, connectivity, bounce rate/conversion rate, geographical location of user, etc. that can help me with the calculation.
Now I would like to find out if these metrics correlate with each other (e.g. if user uses handheld-device, is response time less important?). Furthermore, I want to know if it is somehow possible to calculate the user experience with the help of these metrics.
I thought it could be helpful if I start a questionnaire and ask some people if they like a specific website depending on the metrics I mentioned above. But beforehand I want to have a look at some already performed questionnaires in the internet, but what I've found so far are only empty questionnaire templates.
My question: Does anybody of you know some completed questionnaires concerning the user experience of applications? Any data source that helps me to get a better insight in ux would be helpful.
