Pulse vs SWS

In the SWS survey, net public sat- isfaction with Duterte plunged 18 points to +48 from +66 in June while his net trust rating fell 15 points to +60 from +75.

The poll tallied the biggest satisfaction rating decline among poorest Class E, mostly the victims of his anti-narcotics crackdown.

“SWS says that the steepest drop in satisfaction ratings of the President is in class E. But Pulse Asia says that the approval ratings for the President is highest for Class E. It’s of entirely two different countries,” Contreras said.

In a Twitter post, political analyst Edmund Tayao asked both polling between their surveys.

“Now what else explains the different results of SWS and Pulse Asia surveys?...In statistics, I don’t think it’ll be that exactly the same. But considerable disparity is something else,” Tayao said.

SWS chief Mahar Mangahas justified the difference between SWS’s “satisfaction” rating and what Pulse Asia calls an “approval” rating, which he said were “not the same.”

“The terms ‘ satisfaction’ and ‘approval’ are not the same. Aside from that, feel free to look for contrasts between the two,” Mangahas told TheManilaTimes in an emailed statement.

SWS spokesman Leo Laroza, for his part, told TheTimes that, “SWS of other organizations.”

Pulse Asia meanwhile asked respondents to rate their satisfaction with and trust in Duterte and other
