On October 24, WBUR/MassINC released the results of a new poll, in which respondents from Massachusetts were asked for whom they will vote: Donald Trump or Hillary Clinton.
WBUR/MassINC poll results
According to the results, 57.0% of interviewees plan to give their vote to former Secretary of State Hillary Clinton, whereas 31.0% would vote for billionaire Donald Trump.
The poll was conducted from October 13 to October 16. A total of 502 likely voters responded. There is a sampling error of +/-4.4 percentage points. Considering this error margin, the gap between both candidates is statistically significant.
Putting the results in context
In general, however, you should not have too much faith in the results of single polls, as they may contain large errors. Rather than relying on results from single polls, the best practice scientific advice is to consult combined polls or, even better, the combined PollyVote forecast that draws upon different methods and data.
For the following analysis, we convert the candidates' raw poll numbers into two-party vote shares. This procedure results in figures of 64.8% for Clinton and 35.2% for Trump.
Comparison to other polls
An average of recent polls in Massachusetts sees Clinton at 64.2% of the two-party vote. In comparison to her numbers in the WBUR/MassINC poll Clinton's poll average is 0.6 percentage points worse. This margin is within the poll's margin of error, which suggests that the poll is not an outlier. The latest PollyVote foresees Clinton to gain 64.8% of the two-party vote in Massachusetts.
