In order to hire a certain number of student in an office, I was wondering how much should one supervisor should think about the money involved. To restrict the answer, I'd like to focus in a biology program in a Canadian university.
Beside the stipends (which can be very different depending on the country or the university), what is the "basic" cost of the activity in which a student would need to develop professionally.
By basic cost, I would for example say, paying for conferences, fees of the equipment needed (laboratory accessories, computer, field equipment, office supplies, etc.), cost of publication or any activity you deem necessary to put.
