Elaborations on Level Six: Statistics

Statistical investigation

AO1: Plan and conduct investigations using the statistical enquiry cycle:

• justifying the variables and measures used;
• managing sources of variation, including through the use of random sampling;
• identifying and communicating features in context (trends, relationships between variables, and differences within and between distributions), using multiple displays;
• making informal inferences about populations from sample data;
• justifying findings, using displays and measures.

Further detail on this achievement objective will be added shortly.

Statistical literacy

AO1: Evaluate statistical reports in the media by relating the displays, statistics, processes, and probabilities used to the claims made.

Further detail on this achievement objective will be added shortly.

Probability

AO1: Investigate situations that involve elements of chance:

• comparing discrete theoretical distributions and experimental distributions, appreciating the role of sample size;
• calculating probabilities in discrete situations.

Further detail on this achievement objective will be added shortly.
