# Talk:Moving Average

## Illustrating the concept of moving average

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.

Am I making sense? Cheers, Ottawahitech (discusscontribs) 16:58, 9 October 2020 (UTC)

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.

• ${\displaystyle y1=...,3,4,7,6,7,12,...}$
• ${\displaystyle y2=...,5,6,8,....}$
• ${\displaystyle (3+4+7+6)/4=5}$
• ${\displaystyle (4+7+6+7)/4=6}$
• ${\displaystyle (7+6+7+12)/4=8}$
• ${\displaystyle ....}$

Would be great if you could support in creating some useful graphs for learners and learning tasks.--Bert Niehaus (discusscontribs) 17:11, 9 October 2020 (UTC)
