Hi,

Where does the MR value shown below as 2.14 come from?

Please let me know as it doesn’t make sense if you look at the MR table.

Thank you.

Best Regards,

Hi Sharon,

2.14 is the average of the moving range values. In this case sum up the individual MR values and you get 15. Divide that by 7 and you get 2.14.

Thank you very much. Sometimes it is clear where the information is coming from and sometimes it is not.
