On the time series of the net satisfaction ratings of the Vice-President from the SWS
As time series , we can describe the trend as declining, that is, the people are getting progressively dissatisfied with the Vice-President (the sampling methodology is explained elsewhere by Dr. Mangahas, so I speak here of “the people” as if the entire population is being asked). The start of the time series was on December 2013, and the terminal point here is September 2015, and goes from 62 percent to 33 percent. It can be argued that the time series is not yet finished and that the trend may be reversed. Therefore an alternative would be to give a two time average, a sort of simplified moving average by dividing the time series into two 1 year blocks: from December 2013 to September 2014 as first block; and then from December 2014 to September 2015 as second block; and if the time series continues, to give an annualized comparison. 2014 2015 62 44 73 31 67 42 52 33 Source: SWS current extraction The averages a
