I want to know how many teachers like Dunken Donuts, I am going to use 3 sample instead of the population they are going to be Random picking Convenient picking and Biased picking.
- Random: Julian asked teachers randomly standing in front of the school if they liked dunken donuts.
- Convenient: The first 20 teachers that walk near by me
- Biased: Julian asked teachers going to dunken donuts.
