Creating datasets from Stats NZ

• iNZight was initially designed for New Zealand high schools, allowing students to quickly and easily explore data and understand some statistical ideas (using the companion program VIT).
• However, iNZight now extends to multivariable graphics, time series, and generalised linear modelling (including modelling of data from complex surveys).
• iNZight is FREE!! That means you can download and use it however you want, for whatever you want. There are absolutely no restrictions. You can download for yourself or redistribute it.
Download iNZight: https://www.stat.auckland.ac.nz/~wild/iNZight/getinzight.php

Who is the report intended to be about? ( population?) is the report aimed at? (interested in the outcomes?)
What is the purpose of the report? data is displayed in the report? What type of data is it – categorical or numerical? are the variables of interest? How are they measured? summary statistics are used in the report? important data or information is missing?
How is the data displayed in the report? Are displays or measures appropriate for the type of data? accurate is the data? do the comments made in the report reflect the given data accurately? 29
