- Suppose a researcher from the School of Education at SU wanted to know whether or not students at SU preferred taking classes online or in person this coming Fall 2020 semester. The researcher plans to collect a sample by preparing an optional online survey sent out via e-mail in which students are asked to circle preferences ”online,” ”in person,” or ”not sure.” There is also comment box in the survey where students can express their opinions and concerns. This method of sampling is an example of which of the following: (i) convenience sampling (ii) voluntary response sampling (iii) stratified random sample (iv) multi-stage sampling8List and explain Four examples each of probabilistic and non- propabilistic sampling techniques.
