The polling isn’t as exciting as it looks

With pollster and electorate volatility apparently running rampant over the last few weeks, it’s worth taking a closer look at exactly what went on.
If we chart the first differences of each pollster since August – the amount that the two party preferred estimate has changed since the previous poll of that pollster – we [...]

New Pollytrend Metric – Phone Pollster Trend

We all know about our Pollytrend chart – where we build a rolling average of the most recent poll from each pollster weighted by sample size, then run an aggressive locally weighted polynomial regression through the results to give us an adaptive trend line. While Pollytrend is good for picking up medium term shifts in [...]

Pollytrend and Odds and Ends

Throwing the last polling cycle’s worth of data into the Pollytrend algorithm, we can see that Newspoll produced no discernible change in the trend line – which is to be expected, since our trend here measures how all polls move together and it can adapt to outliers.

Also worth having a squiz at are three charts [...]

Pollytrend and Vote Floors

Looking at the Labor two party preferred for this polling cycle, we’ve seen Essential Report move +3 over the period, Morgan Face to Face +3 while Newspoll was steady.
Last cycle our Pollytrend line had a hit a turning point, developing a disposition to move towards the Coalition this cycle should the poll results over the [...]

Pollytrend – The August State of Play

During the polling cycle of the last fortnight, on the ALP two party preferred we’ve had Nielsen come in down 2 to 56 from June and Newspoll come in down 2 to 55 from last fortnight. Morgan Face to Face was down 2.5 to 58 from late July/early August and Essential moved down 2 from [...]

Pollytrend – Fading Coalition Edition

Now that this polling cycle is complete, we can update our Pollytrend to see whether the underlying trend in the cumulative polling results have changed.
Throwing in the new data for this fortnight and comparing this cycle’s Pollytrend with where our trend line was last fortnight gives us:

This cycle we’ve had Morgan Phone come in up [...]

Requestathon – long trends edition

Since there’s been a few requests of late, we might as well make it formal. Is there a piece of analysis you’d like to see done, a chart constructed, a graphic made or some other piece of stuff we deal with here gone over again? If so, whack it in comments and we’ll see what [...]

Pollytrend – Where the polling now sits.

The end of the trend is nigh. Plugging the poll figures from this cycle into our Pollytrend algorithm – the locally weighted polynomial regression we run through an All Pollster pooled aggregation weighted by sample size -  shows how  the medium term trend running against the ALP since April has now bottomed out, even popping [...]

Newspoll – on trend or undercooked?

This fortnight’s Newspoll via The Oz comes in with the primaries running 41 (down 2) / 40 (up 2) to Labor, washing out into a two party preferred of 53/47 the same way, a two point drop for the ALP since last fortnight. This comes from sample of 1148 giving an MoE that maxes out [...]

Pollytrend – 6 weeks of ALP decline.

As you can see from the Pollytrend graphic in the sidebar on the right, the government has taken a chunky hit over the last 6 weeks or so. If we blow that out to take in the entire period of the Rudd government, we can see that the Coalition is currently equalling their best period [...]
