Statistics can be very useful for making sense of the information around us and how it might affect us. Statistics looks at the cycle of data handling and the collection of analysed data. This involves a question, a collection of data on that question, a presentation of that data and an analysis of the data (using spread and centre) and interpreting the results. In answering questions, it is important to contextualise findings in order to justify them.
Probability looks at the likelihood of any event(s) happening. The information can help to make decisions. The uses of probability can be seen in the world of sport, insurance and finance among others. Probability can be used to examine how fair an event or series of events might be. It can be evaluated in different ways; using a diagram or a rule-based approach.
This Strand attempts to combine the theoretical aspects of Probability and Statistics with some real-life application.
It is an interesting and accessible topic, useful for all students.
