There are many tools for online surveys and how to analyze the statistics for them. First the tools used vary from free to very expensive. I found SurveyMonkey to be very user friendly and free unless you need some specifics then they will charge for an upgrade. The key to the surveys is to clearly know your objective in order to ask the correct questions. There are many places to find how to write a better survey like this link. The information collected and technology used has increased the use of graphs and data to communicate information to people. There are plenty of places for free software that gives you a statistical analysis online. (Check this link by David Lane). With so many tools to collect and analysis the data it is becoming easier to collect and share the information.
