Data Mining the 2013 COMELEC Results

by Albert Anthony D. Gavino

All this trending hype on the 60-30-10, is just simple math, there is no conspiracy theory to it from a viewpoint of math and statistics, of course there will be variability from precinct to precinct. 

things that you should consider before making your conclusions

1. Provide Statistical Power Analysis Estimates like Sample Power

A simple explanation from the Indiana University website says that "statistical power analysis estimates the power of the test to detect a meaningful effect, given sample size, test size (significance level), and standardized effect size." 


Sample Power used for Two sample proportions, two tailed with
alpha at 0.10
Sample power software are tools that we can show the general readers that statistics can prove certain accuracy over COMELEC results, by providing COMELEC data from each precinct. (No I wont do that since that would be tedious to do, but a team of individuals may likely do so)
2. Show the Data sheet

By a few margin, computing by means of excel you would probably be getting the same results, yes its close to 60-30-10, If you would get all the total votes. Its just pure math, not based on conspiracy theories.


3. Compare your results by comparing it to the top 12 Senatoriables

NAME PARTY LIST TOTAL VOTES
POE, GRACE PNOY       16,340,333
LEGARDA, LOREN (NPC) PNOY       14,942,824
ESCUDERO, CHIZ PNOY       14,137,127
CAYETANO, ALAN PETER (NP) PNOY       14,129,783
BINAY, NANCY (UNA) UNA       13,310,851
ANGARA, EDGARDO (LDP) PNOY       12,853,305
AQUINO, BENIGNO BAM (LP) PNOY       12,376,372
PIMENTEL, KOKO (PDP) PNOY       11,846,088
TRILLANES, ANTONIO IV (NP) PNOY       11,389,173
VILLAR, CYNTHIA HANEPBUHAY (NP) PNOY       11,070,265
EJERCITO ESTRADA, JV (UNA) UNA       11,010,630
HONASAN, GRINGO (UNA) UNA       10,620,981
PNOY    121,325,856 79%
UNA     32,701,876 21%
   154,027,732 100%

Results show that 80 percent in the top 12 came from the PNOY party list while only 20 percent came from the opposition (UNA). 

4. Plan for future research

Purugganan says that there is much that we can learn from Comelec's election data."In all this furor, I think political analysts are missing something important: that, while votes for individual senators may be different in different regions, the country may be pretty much coalesced into clear pro- and anti-administration voting blocs. This may actually mean that we do have such a thing as national parties that voters across the country vote for," he said


By going through these statistics, party lists have become an important variable in predicting who is most probable to go into the Senatorial top 12. Other factors also have to be considered like the impact of Positive Brand Family Names like BINAY and POE.
