Morgan Poll Analysis – Page: Online : 25-Oct-18
Roy Morgan CEO Michele Levine two days before the Wentworth by-election on Sky News’ new political show "Conroy & Kroger" when asked why she was so critical of cheap polls said: "They may be cheaper, but I can’t really see any point in doing a poll that is going to get the wrong answer. And this is not, as somebody was saying earlier, about people not wanting to tell the truth or in fact lying when they get polled, it’s not that at all, it’s just that these modern new silly ways of polling which are either robo-polls or telephone polls which only get a small proportion of the population or online polls with commercial panels of people who volunteer to be part of it, they only get a really small piece of the population." A stunning example is provided by the Greenpeace ReachTel robo-poll results which last week was reported on by Carly Earl for the Guardian prior to the Wentworth by-election. The Greenpeace ReachTel robo-poll primary vote predictions were significantly in error for several of the leading candidates. Out by more than 10% for Liberal Dave Sharma and ALP candidate Tim Murray and out by more than 3% for the two Independent candidates Kerryn Phelps and Licia Heath. The ReachTel robo-poll’s prediction for the critical two candidate preferred result was even further out. Not only did the two-candidate preferred result compound the error made by being over 10% out on the primary vote for Liberal candidate Dave Sharma and ALP candidate Tim Murray but the preference flows were a further source of error and meant the poll was completely wrong when predicting the two-candidate preferred result between Phelps and Sharma.
