Thanks for your kind reply! I want to work in a pharmacy company and I'm not sure what kind of work I really enjoy. I heard that the biostatisics field may be more promising in the future. On the other hand, PhDs usually have better career promotion. That is why I feel hard to make a choice.
I am admitted to Columbia University, majoring in Biostatistics. And Ohio State University offers me a PhD position, including scholarship and tution waive. I want to know which choice is better for my future career?
