Investigating and modelling time series
General Maths Units 3 and 4 (2023+)
This is the second video in a series of 5 which looks at Time Series for the Further Maths Units 3 and 4 course. To be able to find trends in data it makes sense to smooth the random fluctuations. This can be done in a number of ways. The first I look at is through mean smoothing. I look at both odd numbers of data and even numbers of data items using examples for each. I conclude the video, like all others, by solving some VCAA questions which relate directly to this content area.
