13STAT

NCEA Level 3 Statistics and Probability

Subject Description

Teacher in Charge: Mrs M. Johnstone.

What is Statistics?

We live in an increasingly data-rich and digital world. Computers allow us to collect and store information in quantities that previously would not even have been dreamt of. However, raw, undigested data stored on computers is useless until people can start to make sense of it.

Statistics is the human side of the digital revolution, an information science, the art and science of extracting meaning from seemingly incomprehensible data. Statistics applies to almost any field, which is why some training in statistics can help make you more effective and more employable, regardless of the career direction you choose.

Statistics is about investigation: asking questions, designing ways to collect data to answer those questions, collecting data, making sense of what the data say to produce sensible answers.

The aim of the course is to introduce and develop basic mathematical and statistical skills appropriate for students interested in any field where the collection, analysis and interpretation of quantitative data is important. 

 The course will consolidate and extend upon work introduced in Year 12 on basic statistical and probability methods, and extend students’ abilities to tackle simple modelling and problem-solving situations.  The course will develop students’ awareness both of the wide range of applications of statistics and probability and of the reason for its usefulness.

Careers and pathways:

Statisticians make sense of data and use those insights to explain what is observed and predict what is as yet unknown. There are many avenues for study and work, from statistical theory to its application in biology, climate science, medicine, the social sciences, physics, agriculture, finance and economics, and even history and archaeology.

What the course is like:

There is more reading and writing than calculating in Statistics. The course consists of  three internals, which involve writing a full statistical investigation report, and two externals – one involves mainly calculations and the other requires knowledge of concepts.
