At last, I managed to finish the draft. A lot of changes were made in the result section and I need to rewrote the whole discussion. Changing the result section requires me to recheck all those numbers and calculation. At the moment, I am tired of seeing those numbers again. In statistics, if you change one small figure, it will affect the whole calculation. Chain reaction. I will be waiting for the reply from my supervisor and hopefully, there won't be any major changes required.
