Achievement objectives

What has changed:

# Achievement objective S8-3

In a range of meaningful contexts, students will be engaged in thinking mathematically and statistically. They will solve problems and model situations that require them to:

• Evaluate a wide range of statistically based reports, including surveys and polls, experiments, and observational studies:
• A. critiquing causal-relationship claims
• B. interpreting margins of error.

## Indicators

A. Critiquing causal-relationship claims:

B. Interpreting margins of error:

The approach here is new to the statistics curriculum. It is based on making informed approximations or rules of thumb to interpret reported margins of error and is linked to confidence intervals.

## Progression

S8-3 links from S7-3.

## What is new/changed?

• Critiquing causal-relationship claims.
• Interpreting margins of error.

## Assessment for qualifications

NCEA achievement standards at levels 1, 2 and 3 have been aligned to the New Zealand Curriculum. Please ensure that you are using the correct version of the standards by going to the NZQA website.

The NZQA subject-specific resources pages are very helpful. From there, you can find all the achievement standards and links to assessment resources, both internal and external.
