Thank you for the video. Where is the 2.68 value you mentioned come from?

[@dr.rahman107]

Thanks for watching the video. Z score of 2.68 is considered to be within 99% of the normal distribution of a bell curve. Therefore, its suggested as a cut off point. You can further check its details from internet.

After deleting the outliers the validity of results significantly dropped by more than 8%, is it okay?
