Short term negative trends

There were a number of comments criticising the short time period and a lack of comparison as a % of population.

Data presentation matters. The graph is not wrong but potentially misleading for people who make snap conclusions without closer interpretation esp on social media (myself inclu).

OK, I see now the rationale for the original graph – to show the comparative drop in hunger/poverty/etc over the past 25 yrs. But wouldn’t this graph be more meaningful, at a glance? (pollution not inclu cus I didn’t understand what it meant in original graph)

Poll trends

Polls are useful indicators, albeit backward looking. Trends are also worth keeping an eye on, but they can disguise sudden shifts.

David Farrar tweeted on a post at Kiwiblog:

This is quite misleading. I don’t know whether this is deliberate or not but the timing of this is questionable. August polls are already out of date. Farrar is National’s pollster.

There has been three public polls in September that add a lot to knowledge of poll trends.

Opinion polling for the New Zealand general election, 2017 is more up to date, and much more informative.

This shows that the dramatic Labour upswing has been sustained in September, and National support is diving.

It also highlights the Green dive in support, and shows that so far there is no sign of the  much touted late campaign improvement for NZ First.
