Theoretical sampling (qualitative: sampling for content analysis, quantitative analysis. Two fundamental types of samples: probability samples. Possible to draw valid generalizations from sample to population. Difficult to locate populations (small scale qualitative) Very difficult to draw valid generalizations from sample to population. Types of non-probability sampling: convenience sampling: cases are included because they are readily available take part. Ex: one could go to a mall and administer a survey to anyone willing to. Problem: one cannot generalize the results to some larger population. Although, very unlikely to be representative of the population (introducing a bias: quota sampling: involves collecting a specified number of samples to match the proportions of people in different categories in the population class, etc. groups.
