Developing good research requires the establishment of a sample that is representative of the population you are evaluating. Using the online Ashford Library databases, identify an article that selects a sample from which research is conducted using ethical principles. Briefly describe what type of sample the research utilizes and what methods they use to collect the sample. Determine if you think this is a representative sample and if you think the methods used to get the sample were scientific and ethical. Support your reasoning with appropriate resources. Cite your research. Respond to at least two of your classmates postings.
