This is the third video in the series which deals with Time Series for the Further Maths Units 3 and 4 course. Building on the knowledge gained in the previous two videos, I now look at how to smooth data using moving medians. I look at 3-, 5- and 7 moving medians. A range of examples are used from the Cambridge textbooks and the video concludes with solutions to some of the more recent VCAA exam questions. Watching this video will see your exam scores rocket!
