Please feel free to use this site however you wish, with the provisos that:
- downloaded PDF files are unmodified, and retain the link to this site;
- none of these resources are re-used as part of a site that requires a subscription or fee; and
- if you find errors in any of the content, you email to let me know!
While the reports used on this site obviously do not belong to me, I would not recommend using them for assessment purposes, since too much of the evaluation of these reports is on this site.

Assessment Structure
Assessment Structure
A response to 91266 "Evaluate a statistical report" could consist of three sections.
A) Identify the PURPOSE of the report.
A) Identify the PURPOSE of the report.
Identify the question(s) that the statistical report sets out to answer.
B) Identify and comment on the FEATURES of the report.
B) Identify and comment on the FEATURES of the report.
The features are listed in the achievement standard, and are the same as the five numbered sections of this website.
- Population measures and variables
- Sampling methods
- Survey methods
- Sampling and possible non-sampling errors
- Sample size
While identifying two features is minimally sufficient for the standard, students should comment on more than two features for a less precarious response. If one of the two features was discussed incorrectly, their response would be at Not Achieved level (regardless of how well the rest of their evaluation was written).
C) Identify the FINDINGS of the report.
C) Identify the FINDINGS of the report.
Identify the findings, and comment on whether they are relevant to the purpose.
Evaluate the report as a whole.
Suitable reports
Suitable reports
Suitable reports for this standard need not be too long! Remember that a typical Year 12 student might have a reading speed of 150-225 words per minute.
Often, a statistical report in a newspaper does not cover enough of the five features listed in the standard. However, a little bit of research can often yield the full statistical report.
Not all five features need to be in the report- but the more the better.
I have sometimes found more information in press releases, which might contain links to full reports. The abstract and methodology sections of a full scientific or governmental report are usually where the (statistically) interesting information is hidden.
Often the Analysis sections of scientific and governmental reports have far too much detail for Level 2 students, and statistical techniques they can't access.
A combined report with a news article and (some) background methodology can contain enough information to evaluate the report, without being overwhelming.
The full articles used for the reports on this website are linked and archived here.
If you are looking for interesting, well-written statistically based reports, articles at The Conversation are often written by researchers, and have interesting discussions about the statistical methods used, and links to full research papers.
We should not be expecting our students to read a document like this!
