Illustrating the concept of moving average[edit source]
I just saw an illustration of a moving average on the worldmeters website, so I thought i would share it. If you scroll down to the 2 graphs (Daily New Cases and Daily Deaths) you will see a clickable link at the bottom of both graphs called 7-day moving average.
When the link is clicked one can see a line slowly develop across the graph.
Would suggest to use a simple demo data with CSV2Chart where the learners can calculate the moving average e.g. manually to understand the basic concept together with the chart.
