Good day all,

I am having this issue of outlier removal.

My data shows no univariate outlier when I check using Z-score. Neither do I have value greater than or less than 3.24.

on the other hand, multivariate outlier present ample amounts of outliers which I remove. Despite this, the data do not assume a bell shape.

Trying another method of normalizing data; that is, transformation. In this case an arguably normality was achieved.

My question now is, which method do i need to report in my thesis and, or is there any other ways to deal with outliers?

Thank you in advance.
