Here is my professor’s message. This is my last chance for this subject, Please carefully follow the instruction. There is no requirement for pages as long as it has 25’000 characters. Thank you so much.
“You have to turn in one home assignment of 25 thousand characters on the topic of comparing and contrasting quantitative and qualitative methodologies. What are they used for, which one is more advantageous under which circumstances. You can use e.g. examples, research topics etc. You need minimum 15 academic (!) sources cited for your work. “
