I'm sorry but why did u switch language in the middle of the explanation? I don't understand on the MAD explanation :(

[@EzrhaGodilano]

Hello Faisa, sorry for the confusion. This video was created years ago when it was to cater for my Filipino students. If your question is how to solve the MAD, just use this formula: Running sum of absolute error/Period. Let me know if you have questions :)
