About this poll

The Essential Report summarises the results of a weekly omnibus conducted by Essential Research with data provided by Your Source.  The survey was conducted online from the 24th to 28th October 2013 and is based on 1,075 respondents.

Aside from the standard question on voting intention, this week’s report includes questions on leader attributes, the NSW bushfires, climate change, politicians’ expenses and downloading from the Internet.

The methodology used to carry out this research is described in the appendix on page 14.

Note that due to rounding, not all tables necessarily total 100% and subtotals may also vary.

Methodology, margin of error and professional standards

The data gathered for this report is gathered from a weekly online omnibus conducted by Your Source.  Essential Research has been utilizing the Your Source online panel to conduct research on a week-by-week basis since November 2007.

Each week, the team at Essential Media Communications discusses issues that are topical and a series of questions are devised to put to the Australian public.  Some questions are repeated regularly (such as political preference and leadership approval), while others are unique to each week and reflect media and social issues that are present at the time.

Your Source has a self-managed consumer online panel of over 100,000 members. The majority of panel members have been recruited using off line methodologies, effectively ruling out concerns associated with online self-selection.

Your Source has validation methods in place that prevent panellist over use and ensure member authenticity. Your Source randomly selects 18+ males and females (with the aim of targeting 50/50 males/females) from its Australia wide panel.  An invitation is sent out to approximately 7000 – 8000 of their panel members.

The response rate varies each week, but usually delivers 1000+ interviews.  In theory, with a sample of this size, there is 95 per cent certainty that the results are within 3 percentage points of what they would be if the entire population had been polled. However, this assumes random sampling, which, because of non-response and less than 100% population coverage cannot be achieved in practice. Furthermore, there are other possible sources of error in all polls including question wording and question order, interviewer bias (for telephone and face-to-face polls), response errors and weighting. The best guide to a poll’s accuracy is to look at the record of the polling company – how have they performed at previous elections or other occasions where their estimates can be compared with known population figures. In the last poll before the 2010 election, the Essential Report estimates of first preference votes were all within 1% of the election results.

The Your Source online omnibus is live from the Wednesday night of each week and closed on the following Sunday.  Incentives are offered to participants in the form of points. Essential Research uses the Statistical Package for the Social Sciences (SPSS) software to analyse the data.  The data is weighted against Australian Bureau of Statistics (ABS) data.
