Hi,
I am trying to display the simple moving average of my data over a period of 3. However, the moving average ignores my lastest entry of data. It still calculates the moving average of 3 windows, its just that my last line of data is always ignored.
I have attached some images below, and hopefully it would be able to express the problem that I am facing.
When I set the window to 3, the moving average is displayed as 23.67. This means that it is calculated using my values 18+37+16 = 71, and 71/3 = 23.67. From my understanding, the calculation should be 31+16+37 = 84, and 84/3 = 28. This means that the moving average function is not taking in my latest value for calculation.
This is another example, where I set my window to 1 and it displayed 16 instead of 31.
I am unsure of what went wrong. Any thoughts?
Thank you!
