Validity, Reliability, and Sampling

 
The Forum includes several steps:

Identify a “different” research problem that would be best studied using a non-probability sample. 
Discuss why this research problem is best studied using a non-probability sample, and what type of non-probability sample you would likely use.
Find a peer-reviewed journal article (no more than five years old) related to that research problem.
Discuss the sampling strategy/process used in the article.  What details are included, and what information regarding the sampling was ignored?

Instructions for all Forums:
Each week, learners will post one initial post per week.  This post must demonstrate comprehension of the course materials, the ability to apply that knowledge in the real world.  Learners will engage with the instructor and peers throughout the learning week.  To motivate engaged discussion, posts are expected to be on time with regular interaction throughout the week.  All posts should demonstrate college level writing skills. To promote vibrant discussion as we would in a face to face classroom, formatted citations and references are not required.  Quotes should not be used at all, or used sparingly.  If you quote a source quotation marks should be used and an APA formatted citation and reference provided.
