In my qualitative research, I will be using quota and purposive sampling. Quota is where you divide a population into categories and get a pre-set number of cases in each category (Mahboob, 2015, lecture 6). I will be dividing the tourists’ categories into tourists from Niagara and winery tourists. Purposive is…
