New Potentials for Television Analysis

With the release by Statistics New Zealand of the detailed final estimates for the New Zealand Resident Population as at 30th June 2008, we will be updating the audience potentials used for television analysis.
From Sunday 28th December 2008, the updated population potentials will be applied.

Calculation Changes
15 December 2006
AGB Nielsen
Media Research New Zealand is part of a global company that dedicates 100% of its
resources to the provision of independent, reliable and transparent audience measurement
systems. A key initiative is to align local calculation methodologies to increase
the level of consistency between those used in NZ compared to other markets around
the world.
The following three changes will be implemented from 3rd January 2007.
Summary of changes:
|
Topic |
Current Methodology |
New Methodology |
|
Sample Size Reporting |
Sample sizes are rounded down to the nearest whole number. |
Sample sizes will now be the average of the individual daily sample sizes rounded
to the nearest whole number (with xxx.5 rounding up) |
|
Guests not reported in Longitudinal Analysis (Cumulative Audiences, Reach &
Frequency, Ebb & Flow) |
Guests are included if the period being analysed falls completely within a single
2am to 2am day. |
Guests are now always excluded from the analysis. |
|
Calculating thousands for reports containing more than one day |
The average potential across all days in the report is calculated
and then multiplied by the rating (%) to create a thousands figure |
The thousands figure will be calculated using each individual day’s potential.
For reports that have a single time zone spanning more than one day the thousands
for each day will be calculated and then averaged. |
Any reports that have been run using thousands (000’s) prior to 3rd January 2007 will need to be re-run.

Improved Reach & Frequency Methodology in 2006
22 December 2005
During the course of this year we have discussed with the industry our desire to improve the methodology used for longitudinal analysis (reach & frequency and cumulative audiences). The objective is two-fold - to bring us into line with practice in other markets, and to make the analysis more user-friendly.
The current approach of using the middle day sample and applying a continuous sampling rule[1] creates a number of challenges including:
- Reduction of sample sizes as the analysis period increases
- Confusing results in day-after monitoring of campaigns while they are still on air, due to changes in the sample against which the analysis is run.
- Analysis over periods of more than a few weeks generates unreliable results.
- Incompatibility with the methodology used in other markets, which makes performance in the NZ market hard for multi-national advertisers to understand.
The new methodology will :
- Remove the continuous sampling rule
- Replace middle day sample with average daily sample and weights
- Retain the NBD adjustment to ensure reach multiplied by frequency = TARPs
Extensive testing has been conducted, and we are happy to share this analysis with you in the New Year.
Implementation of the new algorithm is scheduled for the end of Quarter 1, 2006. The precise timing will be confirmed in January.
For more information please contact us.
[1] Continuous sampling requires that each panel member in the target audience must be in the reporting sample for 9 out of every 10 days covered by the analysis.

Enhancements to Website
01 December 2005
Phase 1 of the newly redeveloped
AGBNMR website has now been completed, and we are ready for phase 2: this is where
we implement all those requests and suggestions which you, the user, have communicated
to us. This email summarises all changes to the website, effective 1 December 2005.
Before we proceed to the list of changes we would like to thank you all for your
patience as we've refined the new site, and a special thanks to those who gave us
feedback.
Default Report Settings
-
Individual
report default settings are now possible. Click on the Settings icon (far right
on toolbar), choose the variables you wish the report to default to, each time you
login, and click on Save.
Navigation
- View button; must be clicked to generate reports.
When a different variable is selected (eg demos, timeslots, etc) the View button
will change colour to orange alerting you to click it and regenerate the data table.
-
Selecting an Export option has been simplified; click on the Export icon and a separate
box opens with export options, select the option and the export is actioned.
- A new
Information icon has been added; click on the icon see a definition of the current
report selection.
- Help is now displayed on the main navigation bar.
Content
- The
Channel Share and Average Audience reports have each been split into two sets of
reports; one set displays data tables with all demos down the side, and the other
displays data with time periods down the side. The benefit of having these additional
tables is that you can now make quick comparisons across various demos or across
various time periods.
Groups & Lists
- All reports are arranged alpha-numerically
where they are listed.
- Demographics can now be displayed either in groups (eg male,
female, etc), or as a single, alpha-numeric list of all demos.
Security
- Access to
the site will now be available through your personal login details only (username:
email address/ password: userdefined). Generic logins have been de-activated. Please
contact the Helpdesk on 0800 457 226 if you have any difficulty logging in.
Please
continue to provide feedback on the website and contact us if you have any questions.
Audience Potentials: revised date
30 November 2005
Every year we update the audience potentials used for television analysis. The change usually takes place during November, the exact date dependent on when Statistics New Zealand release the detailed, final estimates for the New Zealand Resident Population for the current year. Starting from 2006 we will fix the date for when potentials are updated to be the first Monday in January, meaning that the 2005 update will be delayed by 1 month.
