Examples
Political Allegiance
A sample of voters in an electorate are given the chance of voting for party $\text A$ or party $\text B$.
Their party allegiance is determined both before and after they have been shown a party political broadcast on behalf of each party.
After the broadcast, their allegiance is once more determined.
McNemar's test can then be used to indicate whether the proportion changing from $\text A$ to party $\text B$ is significantly different from that changing from $\text B$ to party $\text A$.
