About this lesson
This is the video everyone has been waiting for and requesting. Seasonal Indices is finally here and it's everything you need to know to help you understand what a seasonal index is, what you use them for and how to interpret them. Referencing the work to that already covered on smoothing we look at how we can reduce seasonality to enable us to find trends and fit trend lines. This video is longer than most, but packs a punch and has lots of worked examples. Another video will follow this one with lots of VCAA questions.
