The Ministry is migrating nzmaths content to Tāhurangi.
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz).
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024.
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

An interval estimate of a population parameter. A confidence interval is therefore an interval of values, calculated from a random sample taken from the population, of which any number in the interval is a possible value for a population parameter.
The word ‘confidence’ is used in the term because the method that produces the confidence interval has a specified success rate (confidence level) for the percentage of times such intervals contain the true value of the population parameter in the long run. 95% is commonly used as the confidence level.
