Pulse Asia made the survey through face-to-face interviews of 1,200 respondents.
1200/103M Pinoys = 0.000012 SAMPLE SIZE,
1200/72M Pinoys aged 15 to 80 = 0.000017 SAMPLE SIZE.

Answers on survey questions within a selected sample population will always be subjective to the opinions of an individual’s influence such as but not limited to: current events, perceptions, politics, mood sways, opinions of other people he listens to (i.e. boss, amo, pets, suot ni Inday, biceps ni crush, etc.), the weather, the ant that bit him while answering the survey questionnaire, at kung tuyo na naman ang ulam nya nung lunch time.
Other hard-to-prove but most probable factors have participation on the results of any given survey, such as but not limited to: the person commissioning the survey and his purpose or agenda, the organization conducting it and their influences, if the survey questionnaire was designed to be leading to form an opinion, and the general atmosphere of fright and suppositions of danger (as projected by PAGASA). An example is shown next on a reaction quote by an unnamed person.
“..why for God’s sake that this time did the SWS and Pulse Asia surveys’ numbers match exactly to the last integer at 91% ? Had they adapted a new and correct surveying and computing methodology at last sa takot kay Digong ?”
Other factors that would support or invalidate any time and event sensitive survey results are, but not limited to:
FACTORS ON THE TIME OF THE SURVEY:
- The survey was conducted from July 2 to 8, 2016 or two days after Duterte took his oath as President.
- During this time, Duterte identified the 5 police generals allegedly involved in illegal drug trade.
FACTORS AFTER THE TIME OF THE SURVEY:
