Explanation / Answer

1- Researchers may find participants for their studies through advertisement in newspaper, recruitment of the students, and advertising in a variety of media. There are several ways to find the participants, but these ways are more convenient, advertising takes much effort but recruitment is better option for getting subjects for the research. Recruitment is more effective method because it increases the possibility to get more subjects, while advertisement doesn't give us surety to get better subjects. Subjects are more motivated to get into the research because of compensation and recruitment provides them compensation. 2- There may be systematic differences on the variety of levels between those who choose to participate and who do not. The participants are informed about their rights before the participation in the research. They get information about the ethics. 3- Self selection is the method of non- probability approach, in this method research choose the participants on the basis of convenience. It arises the problem of inadvertently mistakes, which can affect the data. If the data is not reliable then we cannot generalize the result from that data. Therefore it is true that self selection can bias the results of the study and yield data that are inaccurate and will not generalize to the population.
