Sampling error, however, is oversimplified when presented as a single number in reports that may include subgroups, poll-to-poll changes, lopsided margins and results measured on the difference.

Designers must understand the frequency-domain mechanisms of jitter-induced sampling errors to achieve the optimal system and data converter performance.

You can’t get into an argument about polls without some wise guy whipping out the “margin of error” to shut down the other side. But what is the margin of error, exactly?
