With my current typically tasks, I do not used any survey.
On the part of this topic, i had experienced of survey to share here. Well, when I was in the university, my professor assign us, in the class to do a surveys/poll about travel attraction to selling travel program to the sudent in our university.After we recived the result from this poll, we still need more factor to estimated a probability with some condition. It's not really easy to stratup this project in a sudenly limid time that we have.
How ever, the survey is one of good choice support data to help you clearify and more easy to make your direction of dicesion .
