Fill-in-the Blank: The smaller the ____-_-____ the more _____ a poll is.
Scientific PollingMost politicians today use scientific polls to measure public opinion. Scientific polling involves three basic steps:
1. Selecting a sample of the group to be questioned2. Presenting a carefully worded question or questions to the
individuals in the sample.3. Interpreting the results.

Scientific PollingPolling has improved greatly since the 1930s, however it is still far from being completely accurate, and it never will be completely accurate. An election exit poll is a poll taken immediately after voters have exited their polling station. Usually news broadcasters such as Fox News and CNN will conduct exit polls to gain an indication as to how an election has turned out because in some elections the actual results might take days to count.
