The number one problem with surveys is becoming data rich and information poor. Often, data is not easy to come by and so when it starts to accumulate, having something tangible gets us excited. But data is simply points in space that have an inferred relationship by virtue of the questions used to collect it. Having lots of data is data rich, but the back-end work is only beginning.
To turn data into information, start mining for relationships, minimums, maximums, and soon the data sprouts information.
