How does a POLL of POLLS work?

The system, used by Nate Silver’s 538 and Real Clear Politics, focuses on aggregating the largest number of polls and surveys. Then the idea is to calculate an average poll, which should reflect reality with more accuracy.

Moreover, the additional focus of such a system could be more on the trends that could be calculated by comparing the polls of the same resource relative to time.

Let me demonstrate the POLL of POLLS calculation:

With the elections still several months away, few polls have been made public. There is one made for the Zahleh district in the Bekaa (the poll was made by Fghali and published in Al Akhbar newspaper). Here is its finding:

Party name Projected votes Projected percentage
Future Movement 28,004 24.1
Hezbollah 22,654 15.6
FPM (Aoun) 14,612 12.6
Popular bloc (Skaff) 14,074 12.1
Lebanese Forces 14,074 12.1

Fictive poll 1:At this point, such a poll will not be very reliable, and would certainly have certain bias. Thus, having two or more would increase our certainty. For example, I will add two additional fictive polls to illustrate how this site’s projections will work.

Party name Projected percentage
Future Movement 22.1
Hezbollah 16.7
FPM (Aoun) 11.2
Popular bloc (Skaff) 10.5
Lebanese Forces 9.5

Fictive poll 2:

Party name Projected percentage
Hezbollah 19.7
Future Movement 18.9
Lebanese Forces 13.5
FPM (Aoun) 11.5
Popular bloc (Skaff) 9.2

Now if we calculate the poll averages of all three (by applying a simple average formula, in this case (poll 1+2+3)/3 ), our projection accuracy would certainly increase. In this fictive example, this is what the average would look like:


Party name Projected percentage
Future Movement 21.7
Hezbollah 17.2
FPM (Aoun) 11.76
Lebanese Forces 11.7
Popular bloc (Skaff) 10.6

Finally, such a Poll of Polls would inherently be more accurate and less affected by political or methodological biases. Thus, this blog will maintain a POLL of POLLS for all 15 districts, once more than three polls are published for each! The Poll will have it’s own dedicated page, and each update will be published on the main page and on the several attached social media outlets.

Tomorrow, I will further explain how a trend analysis of polls would work. But it should look like this:
