If you’re convinced time has started standing still ever since you started NCEA, this is the internal for you. In this Time Series internal you will draw a graph that shows change over time. Then you will be asked to find some equations and write a report. For example, you might look at how much money New Zealanders spend on recreational activities. You will look at three types of change that happens over time:
(1) How do things change within seasons? (e.g. more spending around Christmas time)
(2) How does change happen over the long-term? (e.g. people are spending more than they used to on average)
(3) Can we forecast what will change in the future?
