Notes on using MovingAverages.xls
I use this to demonstrate the idea of moving averages.
The built in Excel trend function does not give properly plotted Moving Averages.
You can enter your own data in the value column and the Moving Averages and graph should update automatically.
You can also change the 4 where it says "4 Point Moving Averages" to another value and see what happens or make a suitable choice for your own data.
