Question #1) What other factors influence how reliable polling data is?
Some other factors that can influence the reliability of poling data are what kind of interest the polling committee has in a certain outcome of the poll, when the poll was taken for example if the poll pertains to a certain subject the is important in the political election year, the sample size of the poll, the margin allotted for error and how the questions are worded for example if the poll is on the death penalty than how it is worded can affect the outcome of the poll.

Then that number is called. The data is entered into a computer than analyzed later.
Question #3) What changes would you expect to see in the collection of public opinion data over the next several years?
I think that the internet would be a good way because you can reach out to anyplace in the world for a sample, but I think that some of the data could be unreliable. They would have to design a way that the person taking the poll can only do it once so that the data is accurate. I think that there are going to be several changes to how we take polls due to the rapid changing of technology.
