Question

It is not unusual for researchers to use a convenience sample for their study. Consider a study in which the researcher would like to determine how parents working with their children on homework influence the child's school grades. The researcher may consider recruiting friends and relatives to participate in your study because it will be easier to obtain their permission for data collection. What might be some of the limitations of this sampling approach? What are some potential ethical implications to using a convenience sample?

Answer 1

Though this is the question of statistics but i will share some point of views from psychological angle only.

Ethical implications of such research can be done mostly in the schools and guardians must be made aware about their childrens the impacts of their help in completing tasks.

Regarding limitations , whatever be the sample size but understanding the entire child psychology is impossible . A certain percentage can be identified that those students are benefitted by the interferences of their guardians but it can,t be proved with this research what could be the results of that children if his or her guardian will not involve in completing the tasks . Students intelligency level cant be measured with this approach, failing which it has a negative impact on the ethical implications .
