## Topic 5 - Statistics and Probability (35 hours)

The aim of this topic is to introduce basic concepts. It is expected that most of the calculations required will be done using technology, but explanations of calculations by hand may enhance understanding. The emphasis is on understanding and interpreting the results obtained, in context. Statistical tables will no longer be allowed in examinations. While many of the calculations required in examinations are estimates, it is likely that the command terms “write down”, “find” and “calculate” will be used.

Everyday we use the words 'chance', 'likelihood', 'probability' and 'certain'. These words also describe mathematical probability. This important branch of mathematics helps us to understand risk, and everything from sporting averages to the weather report and the chance of being stuck by lightning.
